Functions

flip

</> 
pub fn flip(fun: fn(a, b) -> c) -> fn(b, a) -> c

Deprecated: This function has been deprecated. Use a function literal instead: `fn(a, b) { fun(b, a) }`

Takes a function that takes two arguments and returns a new function that takes the same two arguments, but in reverse order.

identity

</> 
pub fn identity(x: a) -> a

Takes a single argument and always returns its input value.

tap

</> 
pub fn tap(arg: a, effect: fn(a) -> b) -> a

Takes an argument and a single function, calls that function with that argument and returns that argument instead of the function return value. Useful for running synchronous side effects in a pipeline.
