Struct Host 

pub struct Host { /* private fields */ }

The way back to the recorder: logs, health, results. Cheap to clone and usable from any thread. (A plugin’s stdout belongs to the protocol — never println! in a plugin; use this, or eprintln! for the raw log.)

Implementations

impl Host

pub fn to_writer(w: impl Write + Send + 'static) -> Host

A host writing to w instead of stdout (see crate::testing).

pub fn send(&self, m: &PluginMessage)

pub fn log(&self, level: Level, message: impl Into<String>)

pub fn error(&self, message: impl Into<String>)

pub fn warn(&self, message: impl Into<String>)

pub fn info(&self, message: impl Into<String>)

pub fn debug(&self, message: impl Into<String>)

pub fn status(&self, state: State, message: impl Into<String>)

The plugin’s health, shown in the interface until the next.

pub fn metrics(&self, m: &Metrics)

How the plugin’s work is going (see Metrics): queue, timing, the services it talks to. At most every few seconds.

pub fn call_result( &self, path: &str, outcome: Outcome, message: impl Into<String>, url: impl Into<String>, )

What became of a concluded call.

pub fn call_result_took( &self, path: &str, outcome: Outcome, message: impl Into<String>, url: impl Into<String>, took: Duration, )

The same, and how long the work on it took (an upload’s last try): the recorder tells waiting from uploading by it. crate::CallQueue says it for you.

Trait Implementations

impl Clone for Host

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
