Function decodeAlloc [src]

Decodes a stream of frames from src; returns the decoded bytes. The stream should not have extra trailing bytes - either all bytes in src will be decoded, or an error will be returned. Errors returned: error.DictionaryIdFlagUnsupported if a src contains a frame that uses a dictionary error.MalformedFrame if a frame in src is invalid error.OutOfMemory if allocator cannot allocate enough memory

Prototype

 pub fn decodeAlloc( allocator: Allocator, src: []const u8, verify_checksum: bool, window_size_max: usize, ) error{ DictionaryIdFlagUnsupported, MalformedFrame, OutOfMemory }![]u8

Parameters

allocator: Allocatorsrc: []const u8verify_checksum: boolwindow_size_max: usize

Possible Errors

DictionaryIdFlagUnsupported

MalformedFrame

OutOfMemory
