Struct Retry 

pub struct Retry {
    pub attempts: u32,
    pub first_delay: Duration,
}

How a purse resends a transfer that failed on the way: a lost connection, a timeout, or a mint that was paused, busy or could not store it. Resending is safe, since the mint answers an identical transfer with the identical notes, before or after a rotation, for as long as it remembers the transfer (see Purse::settle).

When the mint answers busy, the next wait is as long as its Retry-After asks, up to 30 seconds, if that is longer; the waits after it double from where they were. A Retry-After on any other answer, such as a proxy’s, changes no wait. The mint answers busy only to a request it did not apply, so with the default and Client::new’s 30-second timeout the last try still ends within 127 seconds of any the mint may have applied, inside the 128 seconds a mint keeps each answer by default, and is answered as before.

Fields

attempts: u32

Tries in all, the first included.

first_delay: Duration

Wait before the second try; it doubles before each further one.
