Function init [src]

When connecting reader to a Writer, buffer should be empty, and Writer.buffer capacity has requirements based on Options.window_len. Otherwise, buffer has those requirements.

Prototype

pub fn init(input: *Reader, buffer: []u8, options: Options) Decompress

Parameters

input: *Readerbuffer: []u8options: Options

Source

  pub fn init(input: *Reader, buffer: []u8, options: Options) Decompress {
    if (buffer.len != 0) assert(buffer.len >= options.window_len + zstd.block_size_max);
    return .{
        .input = input,
        .state = .new_frame,
        .verify_checksum = options.verify_checksum,
        .window_len = options.window_len,
        .reader = .{
            .vtable = if (buffer.len == 0) &direct_vtable else &indirect_vtable,
            .buffer = buffer,
            .seek = 0,
            .end = 0,
        },
    };
}
