Struct InternedSlice 

pub struct InternedSlice<T> { /* private fields */ }

A handle to an interned value in an ArenaSlice.

Implementations

impl<T> InternedSlice<T>

pub fn from_id(id: u32) -> Self

Available on crate feature raw only.

Creates an interned value for the given index.

This is a low-level function. You should instead use the from() API to intern a value, unless you really know what you’re doing.

pub fn id(&self) -> u32

Available on crate feature raw only.

Obtains the underlying interning index.

This is a low-level function. You should instead use the lookup() API, unless you really know what you’re doing.

impl<T> InternedSlice<T>

where T: Default + Copy + Eq + Hash,

pub fn from(arena: &ArenaSlice<T>, value: &[T]) -> Self

Interns the given value in the given ArenaSlice.

If the value was already interned in this arena, its interning index will simply be returned. Otherwise it will be stored into the arena.

impl<T> InternedSlice<T>

pub fn lookup<'a>(&self, arena: &'a ArenaSlice<T>) -> &'a [T]

Retrieves this interned value from the given ArenaSlice.

The caller is responsible for ensuring that the same arena was used to intern this value, otherwise an arbitrary value will be returned or a panic will happen.

Trait Implementations

impl<T> Clone for InternedSlice<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for InternedSlice<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for InternedSlice<T>

Available on crate feature serde only.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> GetSize for InternedSlice<T>

Available on crate feature get-size2 only.

fn get_stack_size() -> usize

Determines how may bytes this object occupies inside the stack.

fn get_heap_size(&self) -> usize

Determines how many bytes this object occupies inside the heap.

fn get_heap_size_with_tracker<T>(&self, tracker: T) -> (usize, T)

where T: GetSizeTracker,

Determines how many bytes this object occupies inside the heap while using a tracker.

fn get_size(&self) -> usize

Determines the total size of the object.

fn get_size_with_tracker<T>(&self, tracker: T) -> (usize, T)

where T: GetSizeTracker,

Determines the total size of the object while using a tracker.

impl<T> Hash for InternedSlice<T>

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<T> Ord for InternedSlice<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> PartialEq for InternedSlice<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> PartialOrd for InternedSlice<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> Serialize for InternedSlice<T>

Available on crate feature serde only.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
