Trait ToValueOptional

pub trait ToValueOptional {
    // Required method
    fn to_value_optional(s: Option<&Self>) -> Value;
}

Trait to convert an Option to a Value for optional types.

Required Methods

fn to_value_optional(s: Option<&Self>) -> Value

Convert an Option to a 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.
