Expand description

Trait for format-specific schema inference.

Each implementation handles a single data format (JSON, CSV, etc.) and can infer an Arrow schema from sample records.

Required Methods§

Source

fn format_name(&self) -> &'static str

Returns the format name this inferencer handles (e.g., "json").

Source

fn infer( &self, samples: &[RawRecord], config: &InferenceConfig, ) -> SchemaResult<InferredSchema>

Infers a schema from sample raw records.

§Errors

Returns SchemaError::InferenceFailed if the samples cannot be parsed or the schema cannot be determined.
