Expand description

A source’s ability to report and provision the prerequisites for streaming a set of tables. Implemented per mechanism (Postgres backs it with a publication); consumed by the CLI (check reports, run ensures) only through this neutral surface.

Required Methods§

Source

fn inspect_coverage<'life0, 'life1, 'async_trait>( &'life0 self, required: &'life1 BTreeSet<QualifiedTable>, ) -> Pin<Box<dyn Future<Output = Result<CoverageReport>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Read-only: report coverage of required against what the source streams, and whether the gap (if any) is manageable. Never mutates anything.

Source

fn ensure_coverage<'life0, 'life1, 'async_trait>( &'life0 self, required: &'life1 BTreeSet<QualifiedTable>, manage: bool, ) -> Pin<Box<dyn Future<Output = Result<CoverageReport>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Provision any missing tables when manage is set and the gap is manageable; otherwise a no-op. Returns the report as observed before acting (so a caller can log what was — or would have been — done). A no-op for an already-satisfied set.

Dyn Compatibility§

This trait is dyn compatible.

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