tuple-fn
This crate provides [TupleFnOnce
], [TupleFnMut
] and [TupleFn
],
corresponding to [FnOnce
], [FnMut
] and [Fn
].
[TupleFnOnce
], [TupleFnMut
] and [TupleFn
] enables functions or closures
to be called with a tuple of arguments.
For example:
use tuple_fn::*;
fn add(a: i32, b: i32) -> i32 {
a + b
}
let sum = add.call_with_args_tuple((1, 2));
assert_eq!(sum, 3);
These three traits should be named as
FnOnceCallWithArgsTupleExt
, FnMutCallWithArgsTupleExt
, FnCallWithArgsTupleExt
by convention, because they are implemented for
all corresponding FnOnce
, FnMut
, Fn
types and act like extension traits.
They are named as TupleFn*
just for simplicity.
