Required Methods

fn is_none(&self) -> bool

fn inner_raw_measure( &self, purpose: &Option<RawEncodePurpose>, ) -> Result<usize, BuckyError>

fn inner_raw_encode<'a>( &self, buf: &'a mut [u8], purpose: &Option<RawEncodePurpose>, ) -> Result<&'a mut [u8], BuckyError>

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.
