Function zstd_safe::dctx_set_parameter

pub fn dctx_set_parameter(
    dctx: &mut DCtx, 
    param: DParameter
) -> Result<usize, usize>

ZSTD_DCtx_setParameter()

Set one compression parameter, selected by enum ZSTD_dParameter.

All parameters have valid bounds. Bounds can be queried using ZSTD_dParam_getBounds().

Providing a value beyond bound will either clamp it, or trigger an error (depending on parameter).

Setting a parameter is only possible during frame initialization (before starting decompression).

return : 0, or an error code (which can be tested using ZSTD_isError()).
