Struct Tok 

pub struct Tok<T: Internable> { /* private fields */ }

A shared instance. Equality comparison costs two pointer comparisons. Ordering is by pointer value.

Panics

If an interner was manually constructed, tokens from different interners cannot be compared and attempting to do so causes a panic.

Since a given Interner uses a single TypedInterner for each type, this is only possible if an Interner or TypedInterner was constructed besides the singleton.

Implementations

impl<T: Internable> Tok<T>

pub fn id(&self) -> NonZeroUsize

The pointer value of the token. If this is equal, equality comparison succeeds.

pub fn interner_id(&self) -> NonZeroUsize

The pointer value of the interner. If this is different, comparison panics.

pub fn usize(&self) -> usize

Cast into usize

pub fn assert_comparable(&self, other: &Self)

Panic if the two tokens weren’t created with the same interner

pub fn interner(&self) -> Arc<TypedInterner<T>>

Get the typed interner that owns this token.

pub fn i<Q>(q: &Q) -> Self

where Q: ?Sized + Eq + Hash + ToOwned<Owned = T>, T: Borrow<Q>,

impl<T: Internable> Tok<Vec<Tok<T>>>

pub fn ev(&self) -> Vec<T>

Extern all elements of the vector in a new vector. If the vector itself isn’t interned, use ev

impl<T: Internable> Tok<Vec<Tok<T>>>

pub fn append(&self, suffix: impl IntoIterator<Item = Tok<T>>) -> Self

Add a suffix to the interned vector

pub fn prepend(&self, prefix: impl IntoIterator<Item = Tok<T>>) -> Self

Add a prefix to the interned vector

Trait Implementations

impl<T: Internable + AsRef<U>, U: ?Sized> AsRef<U> for Tok<T>

fn as_ref(&self) -> &U

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: Internable> Borrow<T> for Tok<T>

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<T: Clone + Internable> Clone for Tok<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Internable + Debug> Debug for Tok<T>

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

Formats the value using the given formatter.

impl<T: Internable + Display> Display for Tok<T>

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

Formats the value using the given formatter.

impl<T: Internable> Hash for Tok<T>

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<T: Internable> Ord for Tok<T>

fn cmp(&self, other: &Self) -> 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: Internable> PartialEq for Tok<T>

fn eq(&self, other: &Self) -> 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: Internable> PartialOrd for Tok<T>

fn partial_cmp(&self, other: &Self) -> 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: Internable> Deref for Tok<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
