Trait Implementations

impl<'arena> Clone for Identifier<'arena>

fn clone(&self) -> Identifier<'arena>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'arena> Copy for Identifier<'arena>

impl<'arena> Debug for Identifier<'arena>

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

Formats the value using the given formatter.

impl<'arena> Display for Identifier<'arena>

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

Formats the value using the given formatter.

impl<'arena> Eq for Identifier<'arena>

impl HasSpan for Identifier<'_>

fn span(&self) -> Span

Returns the source span.

fn start_position(&self) -> Position

A convenience method to get the starting position of the span.

fn start_offset(&self) -> u32

A convenience method to get the starting byte offset of the span.

fn end_position(&self) -> Position

A convenience method to get the ending position of the span.

fn end_offset(&self) -> u32

A convenience method to get the ending byte offset of the span.

impl<'arena> Hash for Identifier<'arena>

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<'arena> Ord for Identifier<'arena>

fn cmp(&self, other: &Identifier<'arena>) -> 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<'arena> PartialEq for Identifier<'arena>

fn eq(&self, other: &Identifier<'arena>) -> 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<'arena> PartialOrd for Identifier<'arena>

fn partial_cmp(&self, other: &Identifier<'arena>) -> 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.
