Trait BackfillSyncBuilder 

pub trait BackfillSyncBuilder<N: ProviderNodeTypes, C>: Send {
    type Backfill: BackfillSync + Unpin + 'static;

    // Required method
    fn build(self, ctx: BackfillContext<N, C>) -> Result<Self::Backfill>;

    // Provided method
    fn recover(&mut self, _provider_factory: &ProviderFactory<N>) -> Result<()> { ... }
}

Builds the BackfillSync the engine hands long-range sync to.

Nodes pick one with EngineNodeLauncher::with_backfill; the default is PipelineBackfill.

Required Associated Types

type Backfill: BackfillSync + Unpin + 'static

The backfill this builder produces.

Required Methods

fn build(self, ctx: BackfillContext<N, C>) -> Result<Self::Backfill>

Builds the backfill from the node’s staged pipeline, block client and database.

Provided Methods

fn recover(&mut self, _provider_factory: &ProviderFactory<N>) -> Result<()>

Recovers from an earlier run that stopped mid-write, before the node checks the database for consistency. A backfill that commits static files and the database separately uses it so a crash between the two isn’t treated as corruption. Does nothing by default.

Dyn Compatibility

This trait is dyn compatible.

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