Function to_bytes_fds_for_signature

source 
pub fn to_bytes_fds_for_signature<B, T>(
    ctxt: EncodingContext<B>,
    signature: &Signature<'_>,
    value: &T,
) -> Result<(Vec<u8>, Vec<RawFd>)>
where
    B: ByteOrder,
    T: Serialize + ?Sized,
Expand description

Serialize T that (potentially) contains FDs and has the given signature, to a new byte vector.

Use this function instead of to_bytes_fds if the value being serialized does not implement Type.

Please note that the serialized bytes only contain the indices of the file descriptors from the returned file descriptor vector, which needs to be transferred via an out-of-band platform specific mechanism.

This function is not available on Windows.
