Module Stdlib.BackoffSource
Randomized exponential backoff mechanism.
Type of backoff values.
Logarithm of the maximum allowed value for wait.

Stdlib.Backoff.t @@ portablecreate creates a backoff value. upper_wait_log, lower_wait_log override the logarithmic upper and lower bound on the number of spins executed by once.
default is equivalent to create ().
once b executes one random wait and returns a new backoff with logarithm of the current maximum value incremented unless it is already at upper_wait_log of b.
Note that this uses the default Stdlib Random per-domain generator.
reset b returns a backoff equivalent to b except with current value set to the lower_wait_log of b.
get_wait_log b returns logarithm of the maximum value of wait for next once.
