Trait ScalarRef 

pub trait ScalarRef<'a>:
    Debug
    + Clone
    + 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".
