Enum partial_io::PartialOp

pub enum PartialOp {
    Limited(usize),
    Unlimited,
    Err(ErrorKind),
}

What to do the next time an IO operation is performed.

This is not the same as io::Result<Option<usize>> because it contains io::ErrorKind instances, not io::Error instances. This allows it to be clonable.

Variants

Limited(usize)

Limit the next IO operation to a certain number of bytes.

The wrapper will call into the inner Read or Write instance. Depending on what the underlying operation does, this may return an error or a fewer number of bytes.

Unlimited

Do not limit the next IO operation.

The wrapper will call into the inner Read or Write instance. Depending on what the underlying operation does, this may return an error or a limited number of bytes.

Err(ErrorKind)

Return an error instead of calling into the underlying operation.
