Required Associated Constants

const DISCRIMINATOR: u8

Required Methods

fn to_metadata_value( self, ) -> GenericMetadataValue<UncheckedUrl, UncheckedOrigin>

fn from_metadata_value( entry: GenericMetadataValue<UncheckedUrl, UncheckedOrigin>, ) -> Result<Self, MetadataConversionError>

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.
