Trait Reporter 

pub trait Reporter {
    // Provided methods
    fn fetch_start(&self, total: Option<u64>) { ... }
    fn fetch_inc(&self, n: u64) { ... }
    fn phase(&self, name: &str) { ... }
}

Observes the progress of an Engine::install_artifact_reported run so a caller (the CLI) can render download bars and phase spinners without this crate depending on a UI crate. All methods have no-op defaults; the unit type () implements it as a fully silent reporter.

Provided Methods

fn fetch_start(&self, total: Option<u64>)

The fetch stage is about to begin; total is the artifact’s declared size in bytes when known (used as the download bar’s length).

fn fetch_inc(&self, n: u64)

n more bytes have been downloaded.

fn phase(&self, name: &str)

A new post-fetch phase has begun (e.g. "verifying", "extracting").

Dyn Compatibility

This trait is dyn compatible.

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

Implementations on Foreign Types
