Trait ScalarRef

pub trait ScalarRef<'a>:
    Debug
    + Clone
    + Copy
    + Send
    + 'a {
    type ScalarType: Scalar<RefType<'a> = Self>;

    // Required method
    fn to_owned_scalar(&self) -> Self::ScalarType;
}

Required Associated Types

type ScalarType: Scalar<RefType<'a> = Self>

The corresponding Scalar type.

Required Methods

fn to_owned_scalar(&self) -> Self::ScalarType

Convert the reference into an owned value.

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.
