[−][src]Struct gcode::Span
A half-open range which indicates the location of something in a body of text.
Fields
start: usize
The byte index corresponding to the item's start.
end: usize
The index one byte past the item's end.
line: usize
The (zero-based) line number.
Methods
impl Span
[src]
pub const PLACEHOLDER: Span
[src]
A placeholder Span
which will be ignored by Span::merge()
and
equality checks.
pub const fn new(start: usize, end: usize, line: usize) -> Self
[src]
Create a new Span
.
pub fn get_text<'input>(&self, src: &'input str) -> Option<&'input str>
[src]
Get the string this Span
corresponds to.
Passing in a different string will probably lead to... strange... results.
pub fn merge(self, other: Span) -> Span
[src]
Merge two Span
s, making sure Span::PLACEHOLDER
spans go away.
pub fn is_placeholder(self) -> bool
[src]
Is this a Span::PLACEHOLDER
?
