Module std.container.array

This module provides an Array type with deterministic memory usage not reliant on the GC, as an alternative to the built-in arrays.

This module is a submodule of std.container.

Example

auto arr = Array!int(0, 2, 3);
writeln(arr[0]); // 0
writeln(arr.front); // 0
writeln(arr.back); // 3

// reserve space
arr.reserve(1000);
writeln(arr.length); // 3
assert(arr.capacity >= 1000);

// insertion
arr.insertBefore(arr[1..$], 1);
writeln(arr.front); // 0
writeln(arr.length); // 4

arr.insertBack(4);
writeln(arr.back); // 4
writeln(arr.length); // 5

// set elements
arr[1] *= 42;
writeln(arr[1]); // 42

Example

import std.algorithm.comparison : equal;
auto arr = Array!int(1, 2, 3);

// concat
auto b = Array!int(11, 12, 13);
arr ~= b;
writeln(arr.length); // 6

// slicing
assert(arr[1 .. 3].equal([2, 3]));

// remove
arr.linearRemove(arr[1 .. 3]);
assert(arr[0 .. 2].equal([1, 11]));

Example

Array!bool packs together values efficiently by allocating one bit per element

Array!bool arr;
arr.insert([true, true, false, true, false]);
writeln(arr.length); // 5

Structs

Name Description
Array Array type with deterministic control of memory. The memory allocated for the array is reclaimed as soon as possible; there is no reliance on the garbage collector. Array uses malloc, realloc and free for managing its own memory.
Array Array specialized for bool. Packs together values efficiently by allocating one bit per element.
