Crate transferred_core 

transferred-core — connector-agnostic types: traits, error type, run report.

Structs

Coercion

A single type coercion applied during a run.

RunReport

Post-run statistics returned by Transfer::run().

Transfer

Orchestrates a single end-to-end run from a Source to a Destination.

Enums

CoercionLevel

Severity of a recorded coercion. Info = Tier 1 lossless. Warn = Tier 2 lossy-structural. Tier 3 (lossy-semantic) coercions are not recorded — they fail the run via ElError::Coercion.

ElError

Root error type. Every fallible operation in el returns Result<T, ElError>. Maps to Python el.ElError at the FFI boundary.

Traits

Destination

A destination. Writes batch partitions atomically and reports stats.

Source

A data source. Yields one or more partitions of Arrow batches.

Type Aliases

BatchStream

Boxed Stream of Arrow batches — one partition’s data.
