Trait Saveable 

pub trait Saveable {
    // Required method
    fn save(&self, context: Context<'_>) -> Result<Value<'_>>;
}

Implemented by any value that can be written into a Value.

This is the bottom of the trait hierarchy and is implemented for:

• Primitive numeric types (signed, unsigned, floats, NonZero*).
• bool, str, String, and Handle.
• Option<T> (serializes None as Value::Null).
• &[T] and Vec<T> (serialize as Value::Array).
• Any T: Save (wraps the produced record in Value::Object with the type’s Save::VERSION).

Most user types should implement Save (which gets a Saveable impl for free via the blanket below) rather than Saveable directly.

Required Methods

fn save(&self, context: Context<'_>) -> Result<Value<'_>>

Serialize self into a Value.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
