Struct moore_common::source::Span

pub struct Span {
    pub source: Source,
    pub begin: usize,
    pub end: usize,
}

A span of locations within a source file, expressed as a half-open interval of bytes [begin,end).

Fields

source: Source

begin: usize

end: usize

Methods

impl Span

fn new(source: Source, begin: usize, end: usize) -> Span

Create a new span from two byte offsets.

fn union<S: Into<Span>>(a: S, b: S) -> Span

Create a new span that covers two spans, i.e. represents the smallest possible span that fully contains both input spans a and b.

fn expand<S: Into<Span>>(&mut self, other: S) -> &mut Self

Modify this range to also cover the entirety of the other range. The other range must lie in the same source as self.

fn begin(&self) -> Location

Return the location just before the first character in this span.

fn end(&self) -> Location

Return the location just after the last character in this span.

fn extract(&self) -> String

Copy the portion of the source file in this span into an owned string.

fn iter<'a>(self, content: &'a Rc<SourceContent>) -> Box<CharIter<'a>>

Obtain an iterator over the extract of the source file describe by this span.

Trait Implementations

impl Copy for Span
