Enum EchoMode 

pub enum EchoMode {
    Normal,
    Password,
    NoEcho,
}

How a text input renders its content - Qt’s QLineEdit::EchoMode.

The mode is a display + clipboard policy only: the underlying TextContent / crate::text_model::TextBuffer always holds the real plaintext so editing, caret motion, undo, and IME keep operating on the true value. extract_text substitutes the display glyphs; lumen_input::type_into_focused gates the clipboard.

• Spawned by <input type="password"> markup (wired by the reconciler onto the same entity that carries TextInput).
• Absent component => EchoMode::Normal.

Variants

Normal

Show the text verbatim (default). Copy / cut are allowed.

Password

Render every scalar as PASSWORD_MASK_CHAR; the plaintext stays in the buffer for editing. Copy / cut are blocked (Qt disables them for non-Normal echo modes so a password can’t be lifted off the clipboard); paste and select-all still work.

NoEcho

Render nothing at all (not even length). Same clipboard block as EchoMode::Password.

Implementations

impl EchoMode

pub fn is_concealed(self) -> bool

true when the mode conceals the content: copy must be suppressed and the glyphs masked.

pub fn display_string(self, plain: &str) -> Cow<'_, str>

The run actually drawn for the plaintext plain.

Measuring, hit-testing, and drawing must all agree on one string, so this is what the shaping producer shapes for a concealed field.

pub fn display_offset(self, plain: &str, plain_byte: usize) -> usize

Byte offset into Self::display_string for a plaintext byte offset. Snaps plain_byte down to a code point boundary first.

pub fn plain_offset(self, plain: &str, display_byte: usize) -> usize

Inverse of Self::display_offset: plaintext byte offset for a byte offset into the displayed run.

Trait Implementations

impl Clone for EchoMode

fn clone(&self) -> EchoMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Component for EchoMode

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have Component<Mutability = Mutable>, while immutable components will instead have Component<Mutability = Immutable>.

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn map_entities<M: EntityMapper>(this: &mut Self, mapper: &mut M)

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns [ComponentRelationshipAccessor] required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add [ComponentHook] for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert [ComponentHook] for this Component if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard [ComponentHook] for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove [ComponentHook] for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn [ComponentHook] for this Component if one is defined.

impl Debug for EchoMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for EchoMode

fn default() -> EchoMode

Returns the “default value” for a type.

impl PartialEq for EchoMode

fn eq(&self, other: &EchoMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
