Struct type_erased_vec::TypeErasedVec

pub struct TypeErasedVec<A: Allocator = Global> { /* fields omitted */ }

A type erased Vec.

Implementations

impl<A: Allocator> TypeErasedVec<A>

pub fn new_in<T>(alloc: A) -> Self

Constructs a new, empty TypeErasedVec. See Vec::new_in.

pub fn with_capacity_in<T>(capacity: usize, alloc: A) -> Self

Constructs a new, empty TypeErasedVec with specified capacity. See Vec::with_capacity_in.

pub fn from_vec<T>(vec: Vec<T, A>) -> Self

Erases the type of vec.

pub fn is_leaked(&self) -> bool

Returns if self is leaked.

pub unsafe fn into_vec<T>(self) -> Vec<T, A>

Converts to Vec<T>.

Safety

T must be the same type used constructing this TypeErasedVec.

Constructors include new, new_in, with_capacity, with_capacity_in, from_vec.

Panics

Panics if self is leaked.

pub unsafe fn get<T>(&self) -> &[T]

Gets a reference to [T].

Safety

See TypeErasedVec::into_vec.

Panics

Panics if self is leaked.

pub unsafe fn get_mut<T>(&mut self) -> VecMut<'_, T, A>

Gets a smart pointer to mut Vec<T>.

Safety

See TypeErasedVec::into_vec.

Panics

Panics if self is leaked.

pub fn allocator(&self) -> &A

Gets a reference to the underlying allocator.

Panics

Panics if self is leaked.

impl TypeErasedVec<Global>

pub fn new<T>() -> Self

Constructs a new, empty TypeErasedVec. See Vec::new.

pub fn with_capacity<T>(capacity: usize) -> Self

Constructs a new, empty TypeErasedVec with specified capacity. See Vec::with_capacity.

pub unsafe fn get_ref<T>(&self) -> VecRef<'_, T>

Gets a smart pointer to Vec<T>.

This is usually not want you want. Check TypeErasedVec::get instead.

This method is only implemented for TypeErasedVec<Global> because we can’t get a Vec back without giving it a allocator.

Safety

See TypeErasedVec::into_vec.

Panics

Panics if self is leaked.

Trait Implementations

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

Formats the value using the given formatter.

impl<A: Allocator> Drop for TypeErasedVec<A>

fn drop(&mut self)

Executes the destructor for this type.
