Struct gcode::Span

#[repr(C)]
pub struct Span {
    pub start: usize,
    pub end: usize,
    pub source_line: usize,
}

The location of something within a string.

Fields

start: usize

The byte index corresponding to the beginning of this Span.

end: usize

The byte index one past the end of the selection.

source_line: usize

Which line does this Span start on?

Methods

impl Span

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

Create a new Span.

pub fn placeholder() -> Span

Get the placeholder Span, representing a location which hasn't been resolved yet or doesn't correspond to a location (e.g. generated code).

pub fn is_placeholder(&self) -> bool

Is this the placeholder Span?

pub fn text_from_source<'input>(&self, src: &'input str) -> Option<&'input str>

Based on this Span, get the sub-string it corresponds to.

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

Merge this Span with another one.
