Struct Params 

#[repr(C)]
pub struct Params {
    pub id: usize,
    pub hmac: *mut u8,
}

Parameters of hmac_finalize

Fields

id: usize

The identifier returned by the associated [hmac_initialize()] call.

This is consumed and invalidated by this call regardless of the return value.

hmac: *mut u8

The pointer to the buffer where the hmac must be written.

Its length is defined by the algorithm:

• 32 bytes for SHA-256.

The pointer may be null, in which case this function deallocates the identifier without computing the hmac.
