Trait ArrowSchemaProvider 

pub trait ArrowSchemaProvider {
    // Required method
    fn get_schema(metadata: Option<HashMap<String, String>>) -> Schema;

    // Provided method
    fn get_schema_map() -> HashMap<String, String> { ... }
}

Provides Apache Arrow schema definitions for data types.

Required Methods

fn get_schema(metadata: Option<HashMap<String, String>>) -> Schema

Returns the Arrow schema for this type with optional metadata.

Provided Methods

fn get_schema_map() -> HashMap<String, String>

Returns a map of field names to their Arrow data types.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
