Value lifecycles

A Mojo value has a beginning and an end. Mojo creates and initializes the value before you use it, then destroys it when it's no longer needed.

Lifecycle methods define what happens at each stage. Use them to control how your types initialize their state, transfer values, and release resources.

Creating values

Construct values with generated and custom initializers.

Initialization state

Understand when a value is initialized and ready to use.

Automatic destruction

Let Mojo destroy values automatically after their last use.

Explicit destruction

Require values to be deliberately destroyed in code.
