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

Byte offset of a node start and end positions in the input stream

Fields

start: usize

end: usize

Implementations

impl Span

pub fn span(start: usize, end: usize) -> Span

Create a new span for a specific location

pub fn none() -> Span

Create a new undefined span that is equal to any other span

pub fn is_none(&self) -> bool

Test if span is undefined

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Span

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

Formats the value using the given formatter.

impl PartialEq for Span

fn eq(&self, other: &Self) -> 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.
