Trait cri_ref::traits::Scheme

pub trait Scheme {
    fn to_cri_id(&self) -> Option<i16>;
    fn to_text_scheme(&self) -> &str;

    fn equals(&self, other: impl Scheme) -> bool { ... }
}

A scheme as is part of every CRI.

Required Methods

fn to_cri_id(&self) -> Option<i16>

Give the CRI registered negative integer for the used scheme, if one exits.

Open questions

More correct would be an nint type that has precisely nint semantics,

fn to_text_scheme(&self) -> &str

Give the textual representation of the scheme

Open questions

Should this be fallible? Not being, this makes it hard for a Scheme implementation to carry unknown schemes around.

Provided Methods

fn equals(&self, other: impl Scheme) -> bool
