Enum ConfigValueError 

pub enum ConfigValueError {
    PermissionDenied,
}

Get the current value of the config key.

The expected schema is a hint to the host what type of value is expected by the guest and can be used by the host to automatically migrate config values to fit the expected schema.

Only keys that are declared by the agent-type are allowed to be accessed. Trying to access an undeclared key will trap, unless the expected type is an option. In that case none is returned.

Getting a local key will get values defined as part of the current component revision + overrides declared during agent creation.

Getting a shared key will get the current value of the key in the environment.
