Struct CaretWord 

pub struct CaretWord { /* private fields */ }

Debounces the word under the caret: it is settled once the same word (same text at the same place) has been under a collapsed caret for SUGGESTION_SETTLE. Typing into the word or moving to another one restarts the wait; moving the caret within the word does not.

Time comes in as an argument so a host drives it from its clock and tests from synthetic instants.

Implementations

impl CaretWord

pub fn observe( &mut self, text: &str, selection: Selection, now: Instant, ) -> bool

Record what is under the caret at now. Returns whether the word changed (and its wait restarted).

pub fn clear(&mut self)

Forget the current word, e.g. when the field loses focus.

pub fn current(&self) -> Option<(Range<usize>, &str)>

The word under the caret and its range, whether settled or not.

pub fn settled(&self, now: Instant) -> Option<(Range<usize>, &str)>

The word under the caret once it has settled at now.

pub fn deadline(&self) -> Option<Instant>

When the current word settles; None without a word.

Trait Implementations

impl Clone for CaretWord

fn clone(&self) -> CaretWord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CaretWord

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

Formats the value using the given formatter.

impl Default for CaretWord

fn default() -> CaretWord

Returns the “default value” for a type.

impl PartialEq for CaretWord

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