Struct TextRange 

pub struct TextRange {
    pub start: usize,
    pub end: usize,
}

A range of text measured in byte offsets, matching Compose’s TextRange.

When start == end, the range is collapsed (cursor position). When start > end, the range is reversed (selection direction matters).

Fields

start: usize

end: usize

Trait Implementations

impl Clone for TextRange

fn clone(&self) -> TextRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TextRange

impl Debug for TextRange

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

Formats the value using the given formatter.

impl Eq for TextRange

impl From<(usize, usize)> for TextRange

fn from((start, end): (usize, usize)) -> Self

Converts to this type from the input type.

impl PartialEq for TextRange

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