Function initParams [src]

Takes ownership of buffer which may be resized with gpa. LZMA was explicitly designed to take advantage of large heap memory being available, with a dictionary size anywhere from 4K to 4G. Thus, this API dynamically allocates the dictionary as-needed.

Prototype

 pub fn initParams( input: *Reader, gpa: Allocator, buffer: []u8, params: Decode.Params, mem_limit: usize, ) !Decompress

Parameters

input: *Readergpa: Allocatorbuffer: []u8params: Decode.Paramsmem_limit: usize
