Enum Attribute 

#[non_exhaustive]
pub enum Attribute {
    Observable,
    Interface(&'static str),
    ResourceType(&'static str),
    Title(&'static str),
    Ct(u16),
    Sz(usize),
    Other(&'static str),
}

A property an advertised resource can have many of.

This corresponds to target attributes in Link Format, and also to properties in CoRAL without being very final yet.

This is a single type with static string out-references, but likely to be generalized later into a trait (but right now it’s insufficiently known what it’ll need to produce).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Observable

Interface(&'static str)

ResourceType(&'static str)

Title(&'static str)

Ct(u16)

Sz(usize)

Other(&'static str)

An arbitrary value rendered verbatim into an Link Format document (between ; or , depending on its position).

It is preferred to emit attributes explicitly: This both supports any non-RFC6690 outputs that can work from that more easily, and dynamic data.

Implementations

impl Attribute

pub fn write_link_format(&self, w: &mut impl Write) -> Result

Serializes the attribute into RFC6690 Link Format.

Any attribute that can be serialized (currently and expectedly: all) produces a single semicolon (;) followed by some key and possibly an equals sign (=) and a (possibly quoted) value.

Trait Implementations

impl Clone for Attribute

fn clone(&self) -> Attribute

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Attribute
