Struct naga::Span

pub struct Span { /* fields omitted */ }

A source code span, used for error reporting.

Implementations

impl Span

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

Creates a new Span from a range of byte indices

Note: end is exclusive, it doesn’t belong to the Span

pub fn subsume(&mut self, other: Self)

Modifies self to contain the smallest Span possible that contains both self and other

pub fn total_span<T: Iterator<Item = Self>>(from: T) -> Self

Returns the smallest Span possible that contains all the Spans defined in the from iterator

pub fn to_range(self) -> Option<Range<usize>>

Converts self to a range if the span is not unknown

pub fn is_defined(&self) -> bool

Check wether self was defined or is a default/unknown span

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Span

fn default() -> Span

Returns the “default value” for a type.

impl From<Location> for Span

fn from(loc: Location) -> Self

Performs the conversion.

impl From<Range<usize>> for Span

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