Struct Span 

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

Fields

offset: usize

The offset in the whole file to calculate the absolute position.

start: usize

The relative start of this Span inside a pattern.

end: usize

The relative end of this Span inside a pattern.

Implementations

impl Span

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

Create a new Span

pub fn abs_start(&self) -> usize

Calculates the absolute start using self.offset + self.start.

pub fn abs_end(&self) -> usize

Calculates the absolute end using self.offset + self.end.

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

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 From<Range<usize>> for Span

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