Trait FormatEncoder 

Source 
pub trait FormatEncoder: Send + Sync {
    // Required methods
    fn input_schema(&self) -> SchemaRef;
    fn encode_batch(&self, batch: &RecordBatch) -> SchemaResult<Vec<Vec<u8>>>;
    fn format_name(&self) -> &str;
}
Expand description

Encodes Arrow RecordBatches into raw bytes.

Required Methods§

Source

fn input_schema(&self) -> SchemaRef

Returns the expected input schema.

Source

fn encode_batch(&self, batch: &RecordBatch) -> SchemaResult<Vec<Vec<u8>>>

Encodes a RecordBatch into a vector of byte records.

Each element in the returned vector represents one serialized record.

§Errors

Returns a schema error if encoding fails.

Source

fn format_name(&self) -> &str

Returns the name of the format this encoder produces (e.g., "json").

Dyn Compatibility§

This trait is dyn compatible.

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