Zig 0.17.0-dev (Split by item)

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 library itself.

count

Count the characters needed for format.

pub fn count(comptime fmt: []const u8, args: anytype) usize

File

lib/std/fmt.zig:615

Code

pub fn count(comptime fmt: []const u8, args: anytype) usize {
    var trash_buffer: [64]u8 = undefined;
    var dw: Writer.Discarding = .init(&trash_buffer);
    dw.writer.print(fmt, args) catch |err| switch (err) {
        error.WriteFailed => unreachable,
    };
    return @intCast(dw.count + dw.writer.end);
