Struct ByteRange 

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

A half-open byte range [start, end) into canonical UTF-8 text.

Fields

start: usize

end: usize

Implementations

impl ByteRange

pub fn new(start: usize, end: usize) -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn contains(&self, other: &ByteRange) -> bool

pub fn validate(&self, text: &str) -> Result<(), RangeError>

Validates that the range is well-formed, inside text, and that both boundaries lie on UTF-8 character boundaries.

This is the single gate through which every source mutation must pass (RFC-015 safety invariant: invalid UTF-8 boundary patches must be impossible).

pub fn slice<'a>(&self, text: &'a str) -> Result<&'a str, RangeError>

Returns the slice of text covered by this range after validation.
