    + 'static {
    // Required methods
    fn as_any(&self) -> &(dyn Any + 'static);

    fn cloned(&self) -> Box<dyn ExtensionOptions>;
    fn set(&mut self, key: &str, value: &str) -> Result<(), DataFusionError>;
    fn entries(&self) -> Vec<ConfigEntry>;
}

An object-safe API for storing arbitrary configuration.

See ConfigExtension for user defined configuration

Required Methods

fn as_any(&self) -> &(dyn Any + 'static)

Return self as Any

This is needed until trait upcasting is stabilized

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Return self as Any

This is needed until trait upcasting is stabilized

fn cloned(&self) -> Box<dyn ExtensionOptions>

Return a deep clone of this ExtensionOptions

It is important this does not share mutable state to avoid consistency issues with configuration changing whilst queries are executing

fn set(&mut self, key: &str, value: &str) -> Result<(), DataFusionError>

Set the given key, value pair

fn entries(&self) -> Vec<ConfigEntry>

Returns the ConfigEntry stored in this ExtensionOptions

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
