Enum nbio::WriteStatus

pub enum WriteStatus<'a, T: ?Sized> {
    Success,
    Pending(&'a T),
}

Returned by the Session write function, providing the outcome of the write action.

The generic type T will match the cooresponding Session::ReadData.

Variants

Success

The write action completed fully

Pending(&'a T)

The write action was not performed or was partially performed.

The returned reference must be passed back into the Session write function for the write action to complete. Whether or not the returned reference may consist of partial data depends on the Session implementation.

If you are looking for a general retry pattern, it is always safe to finish the write by passing this returned reference back into the write function for another attempt, but it is only sometimes appropriate to return the entire original write reference into the write function for a second attempt.
