Trait TryToValue 

pub trait TryToValue<S: ValueSchema> {
    type Error;

    // Required method
    fn try_to_value(self) -> Result<Value<S>, Self::Error>;
}

A trait for converting a Rust type to a Value with a specific schema type. This trait is implemented on the concrete Rust type.

This might return an error if the conversion is not possible, see ToValue for cases where the conversion is guaranteed to succeed (or panic).

This is the counterpart to the TryFromValue trait.

Required Associated Types

type Error

The error type returned when the conversion fails.

Required Methods

fn try_to_value(self) -> Result<Value<S>, Self::Error>

Convert the Rust type to a Value with a specific schema type. This might return an error if the conversion is not possible.

See the ToValue trait for a conversion that always succeeds (or panics).
