Struct gcode::Span

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

A set of byte indices which correspond to the location of a substring in a larger piece of text.

The indices are set up such that &original_text[start .. end] will yield the selected text.

Fields

start: usize

The starting index.

end: usize

The index one past the end of the selected text.

source_line: usize

Which line (zero indexed) does the text start on?

Methods

impl Span

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

Create a new Span.

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

Get the union of two spans.

pub fn len(&self) -> usize

The number of bytes within this span.

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

Given the original text, retrieve the substring this Span corresponds to.
