Module Relude_Function.Infix
The Infix
submodule provides two infix operators for function composition.
open Relude.Function.Infix;
let (<<): ('a => 'b) => ('c => 'a) => 'c => 'b;
The <<
operator returns a function that is the equivalent of calling compose()
with its function arguments.
(f << g)(x)
is the equivalent of f(g(x))
.
let sqrtCompFloor = sqrt << floor;
sqrtCompFloor(4.5) == 2.0;
let (>>): ('a => 'b) => ('b => 'c) => 'a => 'c;
The >>
operator returns a function that is the equivalent of calling flipCompose()
with its function arguments.
(f >> g)(x)
is the equivalent of g(f(x))
.
let floorFlipSqrt = floor >> sqrt;
floorFlipSqrt(4.5) == 2.0;
