Struct intern_all::Tok

pub struct Tok<T: Eq + Hash + Clone + 'static> { /* private fields */ }

A number representing an object of type T stored in some interner. Equality comparison costs two pointer comparisons. Ordering is by pointer value.

Panics

Comparison panics if values from different interners are involved. Since a given Interner uses a single TypedInterner for each type, this is only possible if either multiple Interner or TypedInterner instances are constructed.

Implementations

impl<T: Eq + Hash + Clone + 'static> 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 interner that owns this token. It is safe to use this even if the token was created with Interner.

impl<T: Eq + Hash + Clone + 'static> 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 Interner::ev

impl<T: Eq + Hash + Clone + Send + Sync + 'static> Tok<Vec<Tok<T>>>

pub fn append<'a>( &self, i: &Interner, suffix: impl IntoIterator<Item = &'a T> ) -> Self

Add a suffix to the interned vector

pub fn prepend<'a>( &self, i: &Interner, prefix: impl IntoIterator<Item = &'a T> ) -> Self

Add a prefix to the interned vector

Trait Implementations

Performs copy-assignment from source.

impl<T: Eq + Hash + Clone + 'static + Debug> Debug for Tok<T>

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

Formats the value using the given formatter.

impl<T: Eq + Hash + Clone + 'static> Deref for Tok<T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T: Eq + Hash + Clone + Display + 'static> Display for Tok<T>

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

Formats the value using the given formatter.

impl<T: Eq + Hash + Clone + 'static> 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: Eq + Hash + Clone + 'static> Ord for Tok<T>

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<T: Eq + Hash + Clone + 'static> PartialEq for Tok<T>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: Eq + Hash + Clone + 'static> 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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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