Result

A fast and minimalistic implementation of the Result Monad.

Example

local function operation(condition)
    if condition then
        return Ok(10)
    else
        return Err("'condition' is falsy")
    end
end

local multipliedResult = operation(true):and_then(function(value)
    return Ok(value * 10)
end)

if multipliedResult:is_ok() then
    print(multipliedResult.ok)
end
