Trait w5500_hl::io::Write

pub trait Write<E> {
    // Required methods
    fn write(&mut self, buf: &[u8]) -> Result<u16, E>;
    fn write_all(&mut self, buf: &[u8]) -> Result<(), Error<E>>;
    fn send(self) -> Result<(), E>;
}

Socket writer trait.

Required Methods

fn write(&mut self, buf: &[u8]) -> Result<u16, E>

Write data to the socket buffer, and return the number of bytes written.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error<E>>

Writes all the data, returning Error::OutOfMemory if the size of buf exceeds the free memory available in the socket buffer.

Errors

This method can only return:

• Error::Other
• Error::OutOfMemory

fn send(self) -> Result<(), E>

Send all data previously written with write and write_all.

For UDP sockets the destination is set by the last call to Registers::set_sn_dest, Udp::udp_send_to, or UdpWriter::udp_send_to.
