Trait SchemaExt

pub trait SchemaExt {
    // Required methods
    fn equivalent_names_and_types(&self, other: &Self) -> bool;
    fn logically_equivalent_names_and_types(&self, other: &Self) -> bool;
}

DataFusion-specific extensions to Schema.

Required Methods

fn equivalent_names_and_types(&self, other: &Self) -> bool

This is a specialized version of Eq that ignores differences in nullability and metadata.

It works the same as DFSchema::equivalent_names_and_types.

fn logically_equivalent_names_and_types(&self, other: &Self) -> bool

Returns true if the two schemas have the same qualified named fields with logically equivalent data types. Returns false otherwise.

Use DFSchema::equivalent_names_and_types for stricter semantic type equivalence checking.

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.
