Types reference

These types are available without importing a third-party package. Several live in builtin and are in scope automatically.

Essentials

• Numeric: Int, UInt, Float16, Float32, Float64, SIMD.
• Text: String, StringSlice.
• Collections: List, Dict, Set, Optional, Tuple, Variant.
• Memory: UnsafePointer, Span, InlineArray.
• Errors: Error.

Example

def main():
    var found: Optional[Int] = 4
    if found:
        print(found.value())

Keep in mind

The standard library index groups the same types by module.
