Struct Span 

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

A byte-range span inside a single source file.

Uses u32 offsets to keep Spanned<T> structs compact.

Fields

start: u32

end: u32

file: FileId

Implementations

impl Span

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

pub fn point(offset: u32, file: FileId) -> Self

A zero-width span at a single byte position.

pub fn merge(self, other: Span) -> Self

Merge two spans into one that covers both.

pub fn as_range(self) -> Range<usize>
