Function zstd_sys::ZSTD_initStaticCCtx

pub unsafe extern "C" fn ZSTD_initStaticCCtx(
    workspace: *mut c_void, 
    workspaceSize: usize
) -> *mut ZSTD_CCtx

ZSTD_initStatic*() : Initialize an object using a pre-allocated fixed-size buffer. workspace: The memory area to emplace the object into. Provided pointer must be 8-bytes aligned. Buffer must outlive object. workspaceSize: Use ZSTD_estimate*Size() to determine how large workspace must be to support target scenario. @return : pointer to object (same address as workspace, just different type), or NULL if error (size too small, incorrect alignment, etc.) Note : zstd will never resize nor malloc() when using a static buffer. If the object requires more memory than available, zstd will just error out (typically ZSTD_error_memory_allocation). Note 2 : there is no corresponding “free” function. Since workspace is allocated externally, it must be freed externally too. Note 3 : cParams : use ZSTD_getCParams() to convert a compression level into its associated cParams. Limitation 1 : currently not compatible with internal dictionary creation, triggered by ZSTD_CCtx_loadDictionary(), ZSTD_initCStream_usingDict() or ZSTD_initDStream_usingDict(). Limitation 2 : static cctx currently not compatible with multi-threading. Limitation 3 : static dctx is incompatible with legacy support.
