Struct Mirror 

pub struct Mirror { /* private fields */ }

One mirror target: backends (round-robin) and the share of requests copied to it. Cheap to clone; clones share their state.

Implementations

impl Mirror

pub fn new(name: impl Into<String>, backends: Vec<String>) -> Mirror

Copy every request to backends (round-robin).

pub fn with_live_backends( name: impl Into<String>, backends: Arc<RwLock<Vec<String>>>, ) -> Mirror

Like Mirror::new, with a backend list another component updates (a config-file upstream’s health-checked list).

pub fn percent(self, percent: f64) -> Mirror

Copy only this share of requests (0–100), spread evenly: 25 copies every 4th request, not 25 in a row.

pub fn name(&self) -> &str

pub fn send(&self, request: &Request, connection: &ConnectionInfo) -> bool

Queue a copy of request if it’s in the sampled share; never blocks. true when a copy was queued.
