Struct Symbol 

pub struct Symbol<T = NonZero<u32>>
where
    T: SymbolPrimitive,
{ /* private fields */ }

Our common grammar symbol type.

Implementations

impl<T> Symbol<T>

where T: SymbolPrimitive,

pub fn first() -> Symbol<T>

Returns the symbol with the lowest numeric value.

pub fn usize(&self) -> usize

Returns the symbol’s numeric value.

Panics

May fail on 16-bit platforms in case of overflow for usize.

Trait Implementations

impl<T> Clone for Symbol<T>

where T: Clone + SymbolPrimitive,

fn clone(&self) -> Symbol<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Symbol<T>

where T: Debug + SymbolPrimitive,

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

Formats the value using the given formatter.

impl<T> Default for Symbol<T>

where T: SymbolPrimitive,

fn default() -> Symbol<T>

Returns the “default value” for a type.

impl<T> Deserialize for Symbol<T>

where T: SymbolPrimitive,

fn begin(out: &mut Option<Symbol<T>>) -> &mut dyn Visitor

The only correct implementation of this method is:

impl<T> Hash for Symbol<T>

where T: Hash + SymbolPrimitive,

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 Index<Symbol> for SymbolBitSet

type Output = bool

The returned type after indexing.

fn index(&self, index: Symbol) -> &<SymbolBitSet as Index<Symbol>>::Output

Performs the indexing (container[index]) operation.

impl<T> Into<u32> for Symbol<T>

where T: SymbolPrimitive,

fn into(self) -> u32

Converts this type into the (usually inferred) input type.

impl<T> Ord for Symbol<T>

where T: Ord + SymbolPrimitive,

fn cmp(&self, other: &Symbol<T>) -> 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<T> PartialEq for Symbol<T>

where T: PartialEq + SymbolPrimitive,

fn eq(&self, other: &Symbol<T>) -> 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<T> PartialOrd for Symbol<T>

where T: PartialOrd + SymbolPrimitive,

fn partial_cmp(&self, other: &Symbol<T>) -> 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.

impl<T> Serialize for Symbol<T>

where T: SymbolPrimitive,

fn begin(&self) -> Fragment<'_>

impl<T> Copy for Symbol<T>

where T: Copy + SymbolPrimitive,

impl<T> Eq for Symbol<T>

where T: Eq + SymbolPrimitive,

impl<T> StructuralPartialEq for Symbol<T>

where T: SymbolPrimitive,
