Trait FormatAdapter 

pub trait FormatAdapter {
    // Required methods
    fn name(&self) -> &str;
    fn entities(
        &mut self,
    ) -> impl Iterator<Item = Result<EntityRecord, AdapterError>>;
    fn edges(
        &mut self,
    ) -> impl Iterator<Item = Result<EdgeRecord, AdapterError>>;
    fn warnings(&self) -> &[String];
}

A format adapter for the KG import pipeline.

Implementations parse a source format and yield entity and edge records using the standard EntityRecord/EdgeRecord wire shapes. The adapter writes no database state — its output is consumed by the standard khive kg import pipeline.

Each iterator item is Ok(record) on success or Err(AdapterError) on a per-record parse failure. Non-fatal issues (unknown optional fields, etc.) accumulate internally and are retrievable via FormatAdapter::warnings. Parsing may be eager or lazy depending on the implementation.

Required Methods

fn name(&self) -> &str

Short name of the format handled by this adapter (e.g. "csv", "json").

fn entities( &mut self, ) -> impl Iterator<Item = Result<EntityRecord, AdapterError>>

Iterate over entity records in the source.

fn edges(&mut self) -> impl Iterator<Item = Result<EdgeRecord, AdapterError>>

Iterate over edge records in the source.

fn warnings(&self) -> &[String]

Non-fatal warnings accumulated during parsing (e.g. unknown columns, missing optional fields).

Dyn Compatibility

This trait is not dyn compatible.

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