std.container.util.make
- multiple declarations
Template make
Returns an initialized object. This function is mainly for eliminating construction differences between structs and classes. It allows code to not worry about whether the type it's constructing is a struct or a class.
template make(T)
;

Example
import std .algorithm .comparison : equal;
import std .container;
auto arr = make!(Array!int)([4, 2, 3, 1]);
assert(equal(arr[], [4, 2, 3, 1]));
auto rbt = make!(RedBlackTree!(int, "a > b"))([4, 2, 3, 1]);
assert(equal(rbt[], [4, 3, 2, 1]));
alias makeList = make!(SList!int);
auto slist = makeList(1, 2, 3);
assert(equal(slist[], [1, 2, 3]));
Template make
Convenience function for constructing a generic container.
template make(alias Container, Args...)

Example
forbid construction from infinite range
import std .container .array : Array;
import std .range : only, repeat;
import std .range .primitives : isInfinite;
static assert(__traits(compiles, { auto arr = make!Array(only(5)); }));
static assert(!__traits(compiles, { auto arr = make!Array(repeat(5)); }));
Example
import std .algorithm .comparison : equal;
import std .container .array, std .container .rbtree, std .container .slist;
import std .range : iota;
auto arr = make!Array(iota(5));
assert(equal(arr[], [0, 1, 2, 3, 4]));
auto rbtmax = make!(RedBlackTree, "a > b")(iota(5));
assert(equal(rbtmax[], [4, 3, 2, 1, 0]));
auto rbtmin = make!RedBlackTree(4, 1, 3, 2);
assert(equal(rbtmin[], [1, 2, 3, 4]));
alias makeList = make!SList;
auto list = makeList(1, 7, 42);
assert(equal(list[], [1, 7, 42]));
