Trait ToValue 

pub trait ToValue {
    // Required method
    fn to_value(&self) -> Value;
}

Converts Rust types to Spanner Value.

This trait is used to encode native Rust types into the generic Value representation suitable for transmission to Cloud Spanner (such as in query parameters or mutation values).

Implementations are provided for standard Rust types, mapping them to their appropriate Spanner values. For example, optional types naturally map to Value::Null when they are None.

Required Methods

fn to_value(&self) -> Value

Encodes this Rust type as a Spanner Value.

Implementations are responsible for using the correct value kind for the corresponding data type in Spanner.

Dyn Compatibility

This trait is dyn compatible.

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