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".
