Struct Span

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

Describes the location of a substring within a string.

Fields

start: u32

The start of the substring.

end: u32

The end of the substring.

Implementations

impl Span

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

Create a new span.

pub fn with_src<T>(self, src: T) -> SpanWithSource<T>

Link the underlying span with its source.

pub fn extend_end(self, end: u32) -> Span

Expand the current span to end. If end is less than the current end, then self is returned

pub fn next_window(self, len: u32) -> Span

Get the next window. The next window is defined as starting at the end of self with length end.

pub fn overlap(self, other: Span) -> Option<Span>

Returns a span that overlaps with both self and other or None if there is no overlap.

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 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.
