end: usize

Implementations

impl StringRange

pub(crate) const fn at(position: usize) -> Self

Creates an empty range at position.

pub(crate) const fn between(start: usize, end: usize) -> Self

Creates a range between two UTF-16 positions.

pub(crate) const fn encompassing(first: Self, second: Self) -> Self

Creates the smallest range containing both inputs.

pub(crate) const fn start(self) -> usize

Returns the inclusive start position.

pub(crate) const fn end(self) -> usize

Returns the exclusive end position.

pub(crate) const fn is_empty(self) -> bool

Returns whether the range contains no UTF-16 code units.

pub(crate) const fn len(self) -> usize

Returns the range length in UTF-16 code units.

pub(super) fn byte_range(self, input: &str) -> Option<Range<usize>>

fn byte_index(input: &str, position: usize) -> Option<usize>
