Struct Span 

pub struct Span {
    pub start: u32,
    pub end: u32,
}

A byte range in the source text.

Spans use byte offsets (not character offsets) for efficiency. Both start and end are inclusive-exclusive: [start, end).

Example

use litedoc_core::span::Span;

let span = Span::new(0, 10);
assert_eq!(span.len(), 10);

Fields

start: u32

Starting byte offset (inclusive).

end: u32

Ending byte offset (exclusive).

Implementations

impl Span

pub const fn new(start: u32, end: u32) -> Self

Create a new span from byte offsets.

pub const fn len(&self) -> u32

Get the length of this span in bytes.

pub const fn is_empty(&self) -> bool

Check if this span is empty.

pub const fn contains(&self, offset: u32) -> bool

Check if this span contains a byte offset.

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

Merge two spans into one covering both.

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Span

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Span

fn default() -> Span

Returns the “default value” for a type.

impl PartialEq for Span

fn eq(&self, other: &Span) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
