Struct Presentation 

pub struct Presentation { /* private fields */ }

What a surface can honestly present, and what it had to give up.

A consumer-side result like Degradation, and not on the wire for the same reason.

Implementations

impl Presentation

pub fn degradations(&self) -> &[Degradation]

Every optional demand this surface could not meet, in the order the definition asked for them.

pub fn is_faithful(&self) -> bool

Whether every demand was met.

Named for what a caller wants to know. A surface that dropped a diagram is still usable, but it is not showing what was written, and the difference should be visible rather than inferred from an empty list.
