This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Public Function

Public Function

std.compress.lzma.Decompress.initParams

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

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.

Params

input: *Reader
gpa: Allocator
buffer: []u8
params: Decode.Params
mem_limit: usize
