Struct ArrayRef

Source
pub struct ArrayRef<'a, T> { /* private fields */ }
Expand description

Type-agnostic wrapper for interoperability with a Mun array. This is merely a reference to the Mun array, that will be garbage collected unless it is rooted.

Implementations§

Source§

impl<'array, T: Marshal<'array> + 'array> ArrayRef<'array, T>

Source

pub fn into_raw(self) -> RawArray

Consumes the ArrayRef, returning a raw Mun array.

Source

pub fn root(self) -> RootedArray<T>

Roots the ArrayRef.

Source

pub fn type_info(&self) -> Type

Returns the type information of the array.

Source

pub fn len(&self) -> usize

Returns the number of elements stored in the array

Source

pub fn is_empty(&self) -> bool

Returns true if this array does not contain a single element.

Source

pub fn capacity(&self) -> usize

Returns the length of the array

Source

pub fn iter(&self) -> impl Iterator<Item = T> + 'array
where T: 'array,

Returns an iterator to iterate over the elements of the array.
