Struct DecompressOptions 

pub struct DecompressOptions {
    pub window_max: u64,
    pub force_ignore_checksum: bool,
}

Decoder knobs for decompress_with.

Fields

window_max: u64

Reject frames whose window exceeds this (bytes). Default 128 MiB.

force_ignore_checksum: bool

Skip XXH64 content-checksum VERIFICATION (ZSTD_d_forceIgnoreChecksum).

The 4 checksum bytes are still consumed, so concatenated frames keep parsing; only the comparison is skipped. Default false.

This is a real cost, not a micro-optimisation: xxh64 over the output is the majority of decode time on high-ratio content (measured 61% on a 32 MiB all-zeros frame – 7792 MB/s with verification, 20150 without). Set this only where the transport already guarantees integrity; it disables the frame’s own corruption detection.
