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) ;

Contained Functions

NameDescription
make
make

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...) ;

Contained Functions

NameDescription
make
make

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]));
