Functions

<comptime_function> ::= "comptime" <function_assignment> ;

Dependencies:

<function_assignment>

The <comptime_function> is a function that is evaluated at compile time. It is defined as the "comptime" keyword followed by a <function_assignment>.

Semantics

Since comptime must be resolved at compile time, the function must contain only expressions resolvable at compile time.

comptime fn a() -> u8 {
    1
}

comptime fn b(arg: u8) -> u8 {
    arg * 2
}

comptime fn c(arg: u8) -> u8 {
    a(b(arg))
}

const A = c(1);
const B = c(A);
