Struct Span

Source
pub struct Span {
    pub start: Position,
    pub end: Position,
}
Expand description

Area that an object spans inside a file.

The area cannot be empty.

[pest::Span<'i>] forces us to track lifetimes, so we introduce our own struct.

Fields§

§start: Position

Position where the object starts, inclusively.

§end: Position

Position where the object ends, inclusively.

Implementations§

Source§

impl Span

Source

pub const fn new(start: Position, end: Position) -> Self

Create a new span.

§Panics

Start comes after end.

Source

pub const fn is_multiline(&self) -> bool

Check if the span covers more than one line.

Source

pub fn cmr(&self) -> Cmr

Return the CMR of the span.

Source

pub fn to_slice<'a>(&self, file: &'a str) -> Option<&'a str>

Return a slice from the given file that corresponds to the span.

Return None if the span runs out of bounds.
