Function async_listen::is_transient_error

pub fn is_transient_error(e: &Error) -> bool

Returns true if the error is transient

The transient error is defined here as an error after which we can continue accepting subsequent connections without the risk of a tight loop.

For example, a per-connection error like ConnectionReset in accept() system call means then next connection might be ready to be accepted immediately.

All other errors should incur a timeout before the next accept() is performed. The timeout is useful to handle resource exhaustion errors like ENFILE and EMFILE: file descriptor might be released after some time but the error will be the same if we continue to accept in a tight loop.

This function is most likely should not be used directly, but rather through one of the following combinators:

• log_warnings
• handle_errors
