Struct Loopback 

pub struct Loopback {}

Trait Implementations

impl Clone for Loopback

fn clone(&self) -> Loopback

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Loopback

fn default() -> Loopback

Returns the “default value” for a type.

impl Transform for Loopback

fn get_name(&self) -> &'static str

Name of the transform used in logs and displayed to the user

fn transform<'shorter, 'longer, 'life0, 'async_trait>( &'life0 mut self, chain_state: &'shorter mut ChainState<'longer>, ) -> Pin<Box<dyn Future<Output = Result<Messages>> + Send + 'async_trait>>

where Self: 'async_trait, 'shorter: 'async_trait, 'longer: 'async_trait + 'shorter, 'life0: 'async_trait,

In order to implement your transform you can modify the messages:

impl TransformBuilder for Loopback

fn build( &self, _transform_context: TransformContextBuilder, ) -> Box<dyn Transform>

Builds a single instance of the transform. Shotover will create a new transform instance by calling this method for every time this transform is configured in the topology.yaml.

fn get_name(&self) -> &'static str

Name of the transform used in logs and displayed to the user

fn is_terminating(&self) -> bool

fn validate(&self) -> Vec<String>

Transform specific validation can be implemented here. Any strings returned are considered a validation error that will be logged and cause shotover to fail to startup.
