Buffers

Constructors

this

this(size_t _chunk_length, size_t _max_chunk, bool _use_secure_mem, bool _zeroize_on_free)

This is the same as calling init2 with the given arguments and offset = 0.

this

this(size_t _chunk_length, size_t _max_chunk, size_t _offset, bool _use_secure_mem, bool _zeroize_on_free)

This is the same as calling init3 with the given arguments and chunk_keep = max_chunk.

this

this(size_t _chunk_length, size_t _max_chunk, size_t _chunk_keep, size_t _offset, bool _use_secure_mem, bool _zeroize_on_free)

Initializes Buffers. Each buffer size is given in the |chunk_length|. The maximum number of buffers is given in the |max_chunk|. On reset, first |chunk_keep| buffers are kept and remaining buffers are deleted. Each buffer will have bufs.pos and bufs.last shifted to left by |offset| bytes on creation and reset.

Variables

chunk_keep

size_t chunk_keep;

The number of Chains to keep on reset

chunk_length

size_t chunk_length;

The buffer capacity of each Buffer

chunk_used

size_t chunk_used;

The number of Chains allocated

cur

Chain cur;

Buffer pointer where write occurs.

dont_free

bool dont_free;

true if the buffers were initialized with a pre-allocated ubyte[] which mustn't be freed
