Struct Span 

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

A span representing a range in the source code

Fields

start: usize

Start position of the span

end: usize

End position of the span

Implementations

impl Span

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

Create a new span from start and end positions

pub const fn into_range(self) -> Range<usize>

Convert to a standard range

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 Display for Span

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

Formats the value using the given formatter.

impl From<Range<usize>> for Span

fn from(range: Range<usize>) -> Self

Converts to this type from the input type.

impl From<SimpleSpan> for Span

fn from(span: SimpleSpan<usize>) -> Self

Converts to this type from the input type.

impl From<Span> for SimpleSpan<usize>

fn from(span: Span) -> Self

Converts to this type from the input type.

impl Hash for Span

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
