Struct wasmtime_environ::BoxedSlice

source · [−]

pub struct BoxedSlice<K, V> where
    K: EntityRef,  { /* private fields */ }

Expand description

A slice mapping K -> V allocating dense entity references.

The BoxedSlice data structure uses the dense index space to implement a map with a boxed slice.

Implementations

source

impl<K, V> BoxedSlice<K, V> where
K: EntityRef,

source

pub unsafe fn from_raw(raw: *mut [V]) -> BoxedSlice<K, V>

Create a new slice from a raw pointer. A safer way to create slices is to use PrimaryMap::into_boxed_slice().

Safety

This relies on raw pointing to a valid slice of Vs.

source

pub fn is_valid(&self, k: K) -> bool

Check if k is a valid key in the map.

source

pub fn get(&self, k: K) -> Option<&V>

Get the element at k if it exists.

source

pub fn get_mut(&mut self, k: K) -> Option<&mut V>

Get the element at k if it exists, mutable version.

source

pub fn is_empty(&self) -> bool

Is this map completely empty?

source

pub fn len(&self) -> usize

Get the total number of entity references created.

source

Returns the last element that was inserted in the map.
