Struct SourceSpan

pub struct SourceSpan { /* private fields */ }

Span within a SourceCode

Implementations

impl SourceSpan

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

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 copy 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

Formats the value using the given formatter.

impl From<(SourceOffset, usize)> for SourceSpan

fn from((start, len): (SourceOffset, usize)) -> Self

Converts to this type from the input type.

impl From<(usize, usize)> for SourceSpan

fn from((start, len): (ByteOffset, usize)) -> Self

Converts to this type from the input type.

impl From<Range<usize>> for SourceSpan

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

Converts to this type from the input type.

impl From<RangeInclusive<usize>> for SourceSpan

fn from(range: RangeInclusive<ByteOffset>) -> Self

Panics

Panics if the total length of the inclusive range would overflow a usize. This will only occur with the range 0..=usize::MAX.

impl From<SourceOffset> for SourceSpan

fn from(offset: SourceOffset) -> Self

Converts to this type from the input type.

impl From<usize> for SourceSpan

fn from(offset: ByteOffset) -> Self

Converts to this type from the input type.

impl Hash for SourceSpan

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 Ord for SourceSpan

fn cmp(&self, other: &SourceSpan) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for SourceSpan

fn partial_cmp(&self, other: &SourceSpan) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
