Function libp2p::core::upgrade::read_one [−][src]
pub async fn read_one(
socket: &'_ mut impl Unpin + AsyncRead,
max_size: usize
) -> Result<Vec<u8, Global>, ReadOneError>
Reads a length-prefixed message from the given socket.
The max_size parameter is the maximum size in bytes of the message that we accept. This is
necessary in order to avoid DoS attacks where the remote sends us a message of several
gigabytes.
Note: Assumes that a variable-length prefix indicates the length of the message. This is compatible with what
write_onedoes.
