Extension methods for working with Literal.

Required Methods§

Source

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

Source

fn to_string_owned(&self) -> Result<String, LiteralCastError>

Source

fn to_native<T>(&self) -> Result<T, LiteralCastError>
where T: FromLiteral + Copy + 'static,

Source

fn from_array_ref( array: &Arc<dyn Array>, index: usize, ) -> Result<Literal, Error>

Source

fn bound_to_native<T>( bound: &Bound<Literal>, ) -> Result<Bound<<T as ArrowPrimitiveType>::Native>, LiteralCastError>
where T: ArrowPrimitiveType, <T as ArrowPrimitiveType>::Native: FromLiteral + Copy,

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.
