Trait VecConfigAlloc

pub trait VecConfigAlloc<T>: VecConfig {
    type Alloc: Allocator;

    // Required methods
    fn allocator(buf: &Self::Buffer<T>) -> &Self::Alloc;
    fn buffer_from_parts(
        data: NonNull<T>,
        length: Self::Index,
        capacity: Self::Index,
        alloc: Self::Alloc,
    ) -> Self::Buffer<T>;
    fn buffer_into_parts(
        buffer: Self::Buffer<T>,
    ) -> (NonNull<T>, Self::Index, Self::Index, Self::Alloc);
}

Configuration for Vec types supporting an allocator.

Required Associated Types

type Alloc: Allocator

The allocator instance type.

Required Methods

fn allocator(buf: &Self::Buffer<T>) -> &Self::Alloc

Get a reference to the allocator instance.

fn buffer_from_parts( data: NonNull<T>, length: Self::Index, capacity: Self::Index, alloc: Self::Alloc, ) -> Self::Buffer<T>

Create a Vec buffer instance from its constituent parts.

fn buffer_into_parts( buffer: Self::Buffer<T>, ) -> (NonNull<T>, Self::Index, Self::Index, Self::Alloc)

Disassemble a Vec buffer instance into its constituent parts.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
