Struct regex_syntax::hir::ClassBytesRange

source ·
pub struct ClassBytesRange {
    start: u8,
    end: u8,
}
Expand description

A single range of characters represented by arbitrary bytes.

The range is closed. That is, the start and end of the range are included in the range.

Implementations§

source§

impl ClassBytesRange

source

pub fn new(start: u8, end: u8) -> ClassBytesRange

Create a new byte range for a character class.

The returned range is always in a canonical form. That is, the range returned always satisfies the invariant that start <= end.

source

pub fn start(&self) -> u8

Return the start of this range.

The start of a range is always less than or equal to the end of the range.

source

pub fn end(&self) -> u8

Return the end of this range.

The end of a range is always greater than or equal to the start of the range.

source

pub fn len(&self) -> usize

Returns the number of bytes in this range.
