Struct ArenaSlice 

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

Interning arena for slices of type T.

Implementations

impl<T> ArenaSlice<T>

pub fn with_capacity(slices: usize, items: usize) -> Self

Available on crate feature raw only.

Creates a new arena with pre-allocated space to store at least the given number of slices, totalling the given number of items of type T.

pub fn slices(&self) -> usize

Available on crate feature raw only.

Returns the number of slices in this arena.

Note that because ArenaSlice is a concurrent data structure, this is only a snapshot as viewed by this thread, and the result may change if other threads are inserting values.

pub fn items(&self) -> usize

Available on crate feature raw only.

Returns the total number of items of type T in this arena.

Note that because ArenaSlice is a concurrent data structure, this is only a snapshot as viewed by this thread, and the result may change if other threads are inserting values.

pub fn is_empty(&self) -> bool

Available on crate feature raw only.

Checks if this arena is empty.

Note that because ArenaSlice is a concurrent data structure, this is only a snapshot as viewed by this thread, and the result may change if other threads are inserting values.

impl<T> ArenaSlice<T>

where T: Default + Copy + Eq + Hash,

pub fn push_mut(&mut self, value: &[T]) -> u32

Available on crate feature raw only.

Unconditionally push a value, without validating that it’s already interned.

impl<T> ArenaSlice<T>

where T: GetSize,

pub fn print_summary(&self, prefix: &str, title: &str, total_bytes: usize)

Available on crate feature debug only.

Prints a summary of the storage used by this arena to stdout.

Trait Implementations

impl<T> Debug for ArenaSlice<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for ArenaSlice<T>

fn default() -> Self

Returns the “default value” for a type.

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

where T: Default + Copy + Eq + Hash + Deserialize<'de>,

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 ArenaSlice<T>

where T: GetSize,

Available on crate feature get-size2 only.

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

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

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_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> PartialEq for ArenaSlice<T>

where T: Eq + Hash,

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> Serialize for ArenaSlice<T>

where T: Serialize,

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.

impl<T> Eq for ArenaSlice<T>

where T: Eq + Hash,
