Struct Span 

pub struct Span {
    pub start: u32,
    pub end: u32,
}

A half-open byte range [start, end) into some source string.

Fields

start: u32

end: u32

Implementations

impl Span

pub const fn new(start: u32, end: u32) -> Self

pub const fn point(offset: u32) -> Self

pub fn len(self) -> u32

pub fn is_empty(self) -> bool

pub fn union(self, other: Span) -> Span

The smallest span covering both. Useful for building a list node’s span from its children.

pub fn slice<'a>(self, src: &'a str) -> &'a str

pub fn contains(self, offset: u32) -> bool
