Trait ToDFSchema

pub trait ToDFSchema: Sized {
    // Required method
    fn to_dfschema(self) -> Result<DFSchema, DataFusionError>;

    // Provided method
    fn to_dfschema_ref(self) -> Result<Arc<DFSchema>, DataFusionError> { ... }
}

Convenience trait to convert Schema like things to DFSchema and DFSchemaRef with fewer keystrokes

Required Methods

fn to_dfschema(self) -> Result<DFSchema, DataFusionError>

Attempt to create a DSSchema

Provided Methods

fn to_dfschema_ref(self) -> Result<Arc<DFSchema>, DataFusionError>

Attempt to create a DSSchemaRef

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.
