std.functional.adjoin - multiple declarations
- Template adjoin
- Alias adjoin
Template adjoin
Takes multiple functions and adjoins them together. The result is a
std.typecons.Tuple with one element per passed-in function. Upon
invocation, the returned tuple is the adjoined results of all
functions.
Arguments
template adjoin(F...);
Functions
| Function name | Description |
|---|---|
| adjoin |
Note
In the special case where only a single function is provided
(F.length == 1), adjoin simply aliases to the single passed function
(F[0]).
Example
import std.functional, std.typecons; static bool f1(int a) { return a != 0; } static int f2(int a) { return a / 2; } auto x = adjoin!(f1, f2)(5); assert(is(typeof(x) == Tuple!(bool, int))); assert(x[0] == true && x[1] == 2);
Alias adjoin
Takes multiple functions and adjoins them together. The result is a
std.typecons.Tuple with one element per passed-in function. Upon
invocation, the returned tuple is the adjoined results of all
functions.
Declaration
alias adjoin(F...) = F[0];
Note
In the special case where only a single function is provided
(F.length == 1), adjoin simply aliases to the single passed function
(F[0]).
Example
import std.functional, std.typecons; static bool f1(int a) { return a != 0; } static int f2(int a) { return a / 2; } auto x = adjoin!(f1, f2)(5); assert(is(typeof(x) == Tuple!(bool, int))); assert(x[0] == true && x[1] == 2);
