This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Public Function

ensureUnusedCapacity

Public Function
std.array_hash_map.ArrayHashMap.ensureUnusedCapacity
pub fn ensureUnusedCapacity(
            self: *Self,
            gpa: Allocator,
            additional_capacity: usize,
        ) Oom!void

Increases capacity, guaranteeing that insertions up until additional_count more items will not cause an allocation, and therefore cannot fail.
