        endpoint: &str,

The production pieces a use case builds once it knows what they’re for.

Required Methods

fn http_backend( &self, endpoint: &str, timeout: Duration, ) -> Result<Arc<dyn HttpBackend>, Error>

The HTTP backend a session against endpoint sends through, whose non-streaming requests time out after timeout.

fn build_services( &self, region: Region, ) -> Pin<Box<dyn Future<Output = Result<Arc<dyn BuildServices>, Error>> + Send + '_>>

The STS and S3 calls ensure_image makes, with credentials for region.

fn clock(&self) -> Arc<dyn Clock>

The clock a session reads when its builder was given none.

A session a sandbox builds takes the plane’s clock instead, so the lifecycle and the session it hands out read one time source.

fn warn(&self, warning: &str)

Reports a warning no caller is left to receive, such as a Sandbox dropped with its VM still billing.

A use case can’t write to a stream itself, since the driving adapter owns those. It mustn’t panic or block: Drop calls it, and a panic there during an unwind aborts.

Dyn Compatibility

This trait is dyn compatible.

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