Enum cogl::PollFDEvent

#[non_exhaustive]
pub enum PollFDEvent {
    In,
    Pri,
    Out,
    Err,
    Hup,
    Nval,
    // some variants omitted
}

A bitmask of events that Cogl may need to wake on for a file descriptor. Note that these all have the same values as the corresponding defines for the poll function call on Unix so they may be directly passed to poll.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

In

there is data to read

Pri

data can be written (without blocking)

Out

there is urgent data to read.

Err

error condition

Hup

hung up (the connection has been broken, usually for pipes and sockets).

Nval

invalid request. The file descriptor is not open.
