Struct WindowImeSurroundingText 

pub struct WindowImeSurroundingText {
    pub text: Arc<str>,
    pub cursor: u32,
    pub anchor: u32,
}

Best-effort IME surrounding text excerpt.

This is intended for platform bridges that need “text around caret” semantics (e.g. winit’s ImeSurroundingText).

• text MUST exclude any active preedit/composing text.
• cursor/anchor are UTF-8 byte offsets within text (must be on char boundaries).
• text SHOULD be limited to at most 4000 bytes (winit backend constraint).

Fields

text: Arc<str>

cursor: u32

anchor: u32

Implementations

impl WindowImeSurroundingText

pub const MAX_TEXT_BYTES: usize = 4000

pub fn best_effort_for_str(text: &str, cursor: usize, anchor: usize) -> Self

Create a best-effort surrounding text excerpt from a full base-buffer string.

The returned excerpt is bounded to Self::MAX_TEXT_BYTES and the cursor/anchor offsets are relative to the excerpt (UTF-8 bytes).

Trait Implementations

impl Clone for WindowImeSurroundingText

fn clone(&self) -> WindowImeSurroundingText

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowImeSurroundingText

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

Formats the value using the given formatter.

impl Hash for WindowImeSurroundingText

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WindowImeSurroundingText

fn eq(&self, other: &WindowImeSurroundingText) -> 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.
