Struct SourceSpan 

pub struct SourceSpan { /* private fields */ }

Span within a SourceCode

Implementations

impl SourceSpan

pub const fn new(start: SourceOffset, length: SourceOffset) -> SourceSpan

Create a new SourceSpan.

pub const fn offset(&self) -> usize

The absolute offset, in bytes, from the beginning of a SourceCode.

pub const fn len(&self) -> usize

Total length of the SourceSpan, in bytes.

pub const fn is_empty(&self) -> bool

Whether this SourceSpan has a length of zero. It may still be useful to point to a specific point.

Trait Implementations

impl Clone for SourceSpan

fn clone(&self) -> SourceSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceSpan

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

Formats the value using the given formatter.

impl From<(SourceOffset, SourceOffset)> for SourceSpan

fn from(_: (SourceOffset, SourceOffset)) -> SourceSpan

Converts to this type from the input type.

impl From<(usize, usize)> for SourceSpan

fn from(_: (usize, usize)) -> SourceSpan

Converts to this type from the input type.

impl From<Label> for SourceSpan

fn from(label: Label) -> SourceSpan

Converts to this type from the input type.

impl From<Range<usize>> for SourceSpan

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

Converts to this type from the input type.

impl From<Range<usize>> for SourceSpan

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

Converts to this type from the input type.

impl From<SourceOffset> for SourceSpan

fn from(offset: SourceOffset) -> SourceSpan

Converts to this type from the input type.

impl From<SourceSpan> for Range<usize>

fn from(span: SourceSpan) -> Self

Converts to this type from the input type.

impl From<usize> for SourceSpan

fn from(offset: usize) -> SourceSpan

Converts to this type from the input type.

impl Hash for SourceSpan

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 SourceSpan

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