Field Documentation

◆ compress

int(* KlCompress::compress) (KlCompress *self, const char *in, size_t in_len, char **out, size_t *out_len, KlAllocator *alloc)

Single-shot: compress entire buffer into *out.

Allocates output via alloc. Caller owns *out and must kl_free(alloc, *out, *out_len).

Parameters

self	Compression session.
in	Input data.
in_len	Input length.
out	Receives allocated compressed output.
out_len	Receives compressed output length.
alloc	Allocator for output buffer.

Returns: 0 on success, -1 on error.

◆ feed

int(* KlCompress::feed) (KlCompress *self, const char *data, size_t len, int flush, int(*emit)(void *ctx, const char *data, size_t len), void *emit_ctx)

Streaming: feed input, emit compressed output via callback.

Parameters

self	Compression session.
data	Input data (NULL when flush=1 for final).
len	Input length (0 when flush=1 for final).
flush	0 for intermediate chunks, 1 for final flush + trailer.
emit	Callback to receive compressed output chunks.
emit_ctx	Context passed to emit callback.

Returns: 0 on success, -1 on error.

◆ encoding

const char *(* KlCompress::encoding) (KlCompress *self)

Content-Encoding value, e.g. "gzip", "deflate", "zstd".

Returns: Static string, never NULL.

◆ reset

void(* KlCompress::reset) (KlCompress *self)

Reset for reuse (may be NULL if not reusable).

◆ destroy

void(* KlCompress::destroy) (KlCompress *self)

Free all resources.
