pub fn call(i: Input) -> Self::Output
[src]
Call the Func
.
Notice that this does not take a self argument, which in turn means Func
cannot effectively close over a context. This decision trades power for convenience;
a three-trait Fn
heirarchy like that in std provides a great deal of power in a
small fraction of use-cases, but it also comes at great expanse to the other 95% of
use cases.
