AllocatedBuffer

Array based buffer manager. Uses custom allocator to get the data. Limits growth to doubling.

struct AllocatedBuffer (

T

Allocator = GCNoPointerAllocator

size_t floorSize = 8192

) {

import std.experimental.allocator.common : stateSize;;

import std.experimental.allocator : IAllocator, theAllocator;;

import std.experimental.allocator : IAllocator, theAllocator;;

this(Allocator alloc);

void releaseFront(size_t elements);

void releaseBack(size_t elements);

T[] window();

size_t avail();

size_t capacity();

size_t extend(size_t request);

}

Constructors

this this(Allocator alloc): Construct a buffer manager with a given allocator.

Members

Functions

avail size_t avail()
capacity size_t capacity()
extend size_t extend(size_t request): Add more data to the window of currently valid data. To avoid expensive reallocation, use avail to tune this call.
releaseBack void releaseBack(size_t elements): Give bytes back to the buffer manager from the back of the buffer. These bytes can be removed in this operation or further operations and should no longer be used.
releaseFront void releaseFront(size_t elements): Give bytes back to the buffer manager from the front of the buffer. These bytes can be removed in this operation or further operations and should no longer be used.
window T[] window(): The window of currently valid data

Parameters

T: The type of the elements the buffer will use
Allocator: The allocator to use for adding more elements
floorSize: The size that can be freely allocated before growth is restricted to 2x.
Based on concept by Dmitry Olshansky
