Functions

allocate

T[] allocate(size_t len)

Allocate a number of bytes, without initializing them, and return the slice to be filled in. The slice reference is temporary, and valid until the next allocation.

clear

void clear()

Effectively empties the data, but preserves the storage for reuse. Same as setting length to 0.

get

I[] get()

Get a reference to the buffer. Ownership of the buffer is passed to the caller (Appender will not deallocate it after this call).

opOpAssign

void opOpAssign(U item)

~= support.

peek

I[] peek()

As with get, but ownership is preserved. The return value is valid until the next allocation, or until Appender is destroyed.

preallocate

void preallocate(size_t len)

Ensure we can append at least len more bytes before allocating.

putEx

void putEx(U items)

Put elements. Accepts any number of items (and will allocate at most once per call). Items can be of the element type (I), or arrays.

uncheckedPut

void uncheckedPut(U items)

Unsafe. Use together with preallocate().

Properties

capacity

size_t capacity [@property getter]

How many items can be appended without a reallocation.

capacity

size_t capacity [@property setter]

Resize backing buffer to the given capacity.

length

size_t length [@property getter]

How many items have been written so far.

length

size_t length [@property setter]

Set the length (up to the current capacity).

Variables

allocator

Allocator allocator;

The allocator.
