Option and Result

option.sidex

/// An optional value of type `T`.
variant Option<T> {
    /// No value.
    None,
    /// Some value of type `T`.
    Some: T
}

result.sidex

/// A result.
variant Result<T, E> {
    Ok: T,
    Err: E
}

To use Option and Result in your schemas, you have to explicitly import them:

import ::sidex::{option::Option, result::Result}
