Struct DecodeOpts 

pub struct DecodeOpts {
    pub threads: Option<usize>,
    pub governor: Option<Arc<Governor>>,
    pub memory_limit: Option<u64>,
}

Fields

threads: Option<usize>

Worker hint. The governor has final say; this is only a request.

governor: Option<Arc<Governor>>

The shared worker/memory budget. None means single-threaded — a codec parallelises only if handed a governor, never from an ambient global.

memory_limit: Option<u64>

Cap on memory a decoder may ask the allocator for. None means unbounded, which is the library default; the CLI always sets a value.

This exists because three pure codecs size a dictionary buffer from a value the file declares in its own header, before producing any output — measured at 69.35 MB peak RSS for a 60-byte .xz, and 538 MB for a crafted 114-byte .lz that decoded correctly, so the cost came purely from the declaration. --max-ratio cannot see it: that guard counts decoded output bytes and the allocation precedes any output.

Exceeding it is crate::Error::ResourceLimit (exit 6), never Corrupt (exit 5) — the file is not damaged, this build simply will not allocate that much.
