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.

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.
