OTP Field
A row of one-character slots that edit a single passcode.

#Anatomy
Import the component's parts and compose them under its root:
use base_gpui::otp_field::{
OTPFieldInput,
OTPFieldRoot,
};
OTPFieldRoot::new()
.child(
OTPFieldInput::new(),
);
The anatomy is a structural overview. Parts with mutually exclusive modes may need separate instances; each part's section below documents its configuration.
#OTPFieldRoot
Coordinates the component's state and supplies context to its child parts.
use base_gpui::otp_field::OTPFieldRoot;
OTPFieldRoot::new()
.with_field_context(/* context: FieldContext */)
.id("example-id")
.name("name")
.aria_label("aria label")
.length(0)
.default_value(/* default_value: impl Into<SharedString> */)
.value(/* value: impl Into<SharedString> */)
.validation_type("example-id")
.normalize_value(|/* callback arguments */| { /* handle change */ })
.mask(true)
.auto_submit(true)
.disabled(true)
.read_only(true)
.required(true)
.on_value_change(|/* callback arguments */| { /* handle change */ })
.on_value_complete(|/* callback arguments */| { /* handle change */ })
.on_value_invalid("example-id")
.style_with_state(|/* callback arguments */| { /* handle change */ });
#Builders
| Builder | Signature & description |
|---|---|
.new | pub fn new() -> SelfCreates a OTPFieldRoot with its default configuration. |
.with_field_context | pub fn with_field_context(mut self, context: FieldContext) -> Self
Sets the with field context configuration for this part. |
.child | pub fn child(mut self, child: impl Into<OTPFieldChild>) -> Self
Adds one typed child to this part. |
.children | pub fn children(mut self, children: impl IntoIterator<Item = impl Into<OTPFieldChild>>,) -> Self
Adds multiple typed children in iteration order. |
.child_any | pub fn child_any(mut self, child: impl IntoElement) -> Self
Adds one arbitrary renderable child to this part. |
.id | pub fn id(mut self, id: impl Into<ElementId>) -> Self
Sets the stable GPUI element identity. Use a unique value when multiple instances can appear in the same view. |
.name | pub fn name(mut self, name: impl Into<SharedString>) -> Self
Sets the form field name used when serializing or submitting the value. |
.aria_label | pub fn aria_label(mut self, aria_label: impl Into<SharedString>) -> Self
Accessible name for the OTP group. Mirror the visible |
.length | pub fn length(mut self, length: usize) -> Self
Sets the length configuration for this part. |
.default_value | pub fn default_value(mut self, default_value: impl Into<SharedString>) -> Self
Sets the initial value for uncontrolled state. Later user changes are retained by the component. |
.value | pub fn value(mut self, value: impl Into<SharedString>) -> Self
Sets the current controlled value or the value represented by this part, depending on the part's role. |
.validation_type | pub fn validation_type(mut self, validation_type: OTPFieldValidationType) -> Self
Sets the validation type configuration for this part. |
.normalize_value | pub fn normalize_value(mut self, normalize_value: impl Fn(String) -> String + 'static) -> Self
Sets the normalize value configuration for this part. |
.mask | pub fn mask(mut self, mask: bool) -> Self
Sets the mask configuration for this part. |
.auto_submit | pub fn auto_submit(mut self, auto_submit: bool) -> Self
Controls whether auto submit behavior is enabled. |
.disabled | pub fn disabled(mut self, disabled: bool) -> Self
When true, prevents user interaction with this part. |
.read_only | pub fn read_only(mut self, read_only: bool) -> Self
When true, allows presentation and focus behavior without permitting value changes. |
.required | pub fn required(mut self, required: bool) -> Self
Marks the control as required for validation and accessibility state. |
.on_value_change | pub fn on_value_change(mut self, on_value_change: impl Fn(SharedString, OTPFieldChangeDetails, &mut Window, &mut App) + 'static,) -> Self
Registers a callback invoked when value change occurs. |
.on_value_complete | pub fn on_value_complete(mut self, on_value_complete: impl Fn(SharedString, OTPFieldChangeDetails, &mut Window, &mut App) + 'static,) -> Self
Registers a callback invoked when value complete occurs. |
.on_value_invalid | pub fn on_value_invalid(mut self, on_value_invalid: impl Fn(SharedString, OTPFieldChangeDetails, &mut Window, &mut App) + 'static,) -> Self
Registers a callback invoked when value invalid occurs. |
.style_with_state | pub fn style_with_state(mut self, style: impl Fn(OTPFieldRootStyleState, Div) -> Div + 'static,) -> Self
Styles the part from its current behavioral state while preserving separation between behavior and visual design. OTPFieldRoot also supports the GPUI traits implemented in its source, such as standard styling or child composition. |
#OTPFieldInput
Text input integrated with the component's state and behavior.
use base_gpui::otp_field::OTPFieldInput;
OTPFieldInput::new()
.with_otp_field_context(/* context: OTPFieldContext */)
.with_slot_index(0)
.id("example-id")
.style_with_state(|/* callback arguments */| { /* handle change */ });

|---|---|
.new | pub fn new() -> SelfCreates a OTPFieldInput with its default configuration. |
.with_otp_field_context | pub fn with_otp_field_context(mut self, context: OTPFieldContext) -> Self
Sets the with otp field context configuration for this part. |
.with_slot_index | pub fn with_slot_index(mut self, index: usize) -> Self
Sets the with slot index configuration for this part. |
.id | pub fn id(mut self, id: impl Into<ElementId>) -> Self
Sets the stable GPUI element identity. Use a unique value when multiple instances can appear in the same view. |
.style_with_state | pub fn style_with_state(mut self, style: impl Fn(OTPFieldInputStyleState, Div) -> Div + 'static,) -> Self
Styles the part from its current behavioral state while preserving separation between behavior and visual design. OTPFieldInput also supports the GPUI traits implemented in its source, such as standard styling or child composition. |
#Accessibility
Keyboard interaction and accessibility semantics are implemented by the component, independently of visual styling. Known limitations caused by missing GPUI accessibility primitives are documented in the module source and are not silently approximated.
#Stability
Base GPUI is pre-1.0. Builder names and state types may evolve as GPUI and this port mature.
