pub struct Span { /* private fields */ }
Expand description

A source code span, used for error reporting.

Implementations§

source§

impl Span

source

pub const UNDEFINED: Self = _

source

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

Creates a new Span from a range of byte indices

Note: end is exclusive, it doesn’t belong to the Span

source

pub const fn until(&self, other: &Self) -> Self

Returns a new Span starting at self and ending at other

source

pub fn subsume(&mut self, other: Self)

Modifies self to contain the smallest Span possible that contains both self and other

source

pub fn total_span<T: Iterator<Item = Self>>(from: T) -> Self

Returns the smallest Span possible that contains all the Spans defined in the from iterator

source

pub fn to_range(self) -> Option<Range<usize>>

Converts self to a range if the span is not unknown

source

pub fn is_defined(&self) -> bool

Check whether self was defined or is a default/unknown span

source

pub fn location(&self, source: &str) -> SourceLocation

Return a SourceLocation for this span in the provided source.

source§

impl Index<Span> for str

§

type Output = str

The returned type after indexing.
source§

fn index(&self, span: Span) -> &str

Performs the indexing (container[index]) operation. Read more
source§

impl PartialEq for Span

source§

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

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

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