Function isPrimitive [src]

Alias for std.zig.primitives.isPrimitive

Returns true if a name matches a primitive type or value, excluding _. Integer type names like u8 or i32 are only matched for syntax, so this will still return true when they have an oversized bit count or leading zeroes.

Prototype

pub fn isPrimitive(name: []const u8) bool

Parameters

name: []const u8

Example

 test isPrimitive {
    const expect = std.testing.expect;
    try expect(!isPrimitive(""));
    try expect(!isPrimitive("_"));
    try expect(!isPrimitive("haberdasher"));
    try expect(isPrimitive("bool"));
    try expect(isPrimitive("false"));
    try expect(isPrimitive("comptime_float"));
    try expect(isPrimitive("u1"));
    try expect(isPrimitive("i99999999999999"));
}

Source

  pub fn isPrimitive(name: []const u8) bool {
    if (names.get(name) != null) return true;
    if (name.len < 2) return false;
    const first_c = name[0];
    if (first_c != 'i' and first_c != 'u') return false;
    for (name[1..]) |c| switch (c) {
        '0'...'9' => {},
        else => return false,
    };
    return true;
