Struct Span 

pub struct Span {
    pub start_line: u32,
    pub start_col: u32,
    pub end_line: u32,
    pub end_col: u32,
}

A source range. Lines and columns are 1-based; end is inclusive of the last line containing the item.

Fields

start_line: u32

First line (1-based).

start_col: u32

Column on the first line (1-based).

end_line: u32

Last line (1-based, inclusive).

end_col: u32

Column on the last line (1-based).

Implementations

impl Span

pub fn new(start_line: u32, start_col: u32, end_line: u32, end_col: u32) -> Self

Construct a span from line/column pairs.

pub fn compact(&self) -> String

L<start>-L<end> (or L<start> for single-line spans), the compact form used in diagram metadata.

assert_eq!(Span::new(3, 1, 9, 2).compact(), "L3-L9");
assert_eq!(Span::new(4, 1, 4, 9).compact(), "L4");

Trait Implementations

impl Ord for Span

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
