Trait Drain

pub unsafe trait Drain: Buffer {
    type Value;

    // Required method
    unsafe fn remove(&mut self, index: usize) -> Self::Value;
}

Buffer whose values can be drained from.

Safety

Calling Drain::remove remove the value inserted at index index (see [InsertIntoBuffer::insert_into`])

Required Associated Types

type Value

Value to be removed from the buffer

Required Methods

unsafe fn remove(&mut self, index: usize) -> Self::Value

Removes a value from the buffer at a given index and return it.

Safety

A value must have been inserted at this index (see InsertIntoBuffer::insert_into) before calling this method.

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.
