Enum Attr 

pub enum Attr {
    Trusted(Trusted),
    TrustedImpl(Trusted),
    Ignore(Ignored),
    ProvenExternally,
    ShouldFail,
    Qualifiers(Vec<Ident>),
    Reveal(Vec<Ident>),
    InferOpts(PartialInferOpts),
}

An attribute attaches metadata to an item.

Note that some of these attributes correspond to a Rust attribute, but some don’t. For example, when annotating a function, a #[flux::trusted] is mapped to Attr::Trusted because it corresponds to metadata associated to the function, however, a #[flux::spec(...)] doesn’t map to any Attr because that’s considered to be part of the refined syntax of the item.

Note that these attributes can also originate from detached specs.
