Enum MaybeDelayed

pub enum MaybeDelayed<'a> {
    Delayed(Key),
    Immediate(Box<dyn Read + 'a>),
}

A type to represent delayed or immediate apply-filter results.

Variants

Delayed(Key)

Using the delayed protocol, this entry has been sent to a long-running process and needs to be checked for again, later, using the driver::Key to refer to the filter who owes a response.

Note that the path to the entry is also needed to obtain the filtered result later.

Immediate(Box<dyn Read + 'a>)

The filtered result can be read from the contained reader right away.

Note that it must be consumed in full or till a read error occurs.
