Struct Span 

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

A match’s byte span alone, for the paths that carry no captures: eight bytes where a Match is fifty-six, twenty-four of them the registers a plain scan never fills.

Fields

start: u32

Inclusive start byte offset of the match in the input.

end: u32

Exclusive end byte offset of the match in the input.

Implementations

impl Span

pub fn start(&self) -> usize

The start offset as an index.

pub fn end(&self) -> usize

The end offset as an index.

pub fn len(&self) -> usize

How many bytes the span covers.

pub fn is_empty(&self) -> bool

Whether the span covers no bytes.

pub fn range(&self) -> Range<usize>

The matched bytes’ range in the input.

Trait Implementations

impl Clone for Span

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Span

impl Debug for Span

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

Formats the value using the given formatter.

impl Eq for Span

impl From<Span> for Match

fn from(s: Span) -> Self

The span with no captures.

impl FromIterator<Span> for Regs

fn from_iter<I: IntoIterator<Item = Span>>(iter: I) -> Self

Creates a value from an iterator.

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: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.

impl Spanned for Span

fn start(&self) -> usize

The byte offset the match begins at.

fn end(&self) -> usize

The byte offset just past it.

fn captures(&self) -> &[Span]

The register spans, in the order Self::names holds their names.

fn names(&self) -> &[String]

The register names, which belong to the pattern rather than to any one of its matches.

fn history(&self, _name: &str) -> Option<&[Span]>

Every binding the register called name made, oldest first, where it is bound under a repetition; None where it is not, or where the match carries no such bindings.
