Enum AttributeContext 

pub enum AttributeContext<'a> {
    Crate(&'a File),
    File(&'a File),
    Item(&'a Item),
    Variant(&'a Variant),
    Field(&'a Field),
    ImplItem(&'a ImplItem),
}

Variants

Crate(&'a File)

The root of a crate, i.e. the inner attributes of its lib.rs/main.rs.

Distinct from AttributeContext::File (a file-module) because only the crate root carries the primary program’s default identity. Constructed explicitly (never via From) so From<&syn::File> keeps mapping to AttributeContext::File.

File(&'a File)

A file-module, i.e. the inner attributes of a mod foo; living in its own foo.rs.

Item(&'a Item)

A top-level item, such as a struct, enum or inline mod { .. }.

Variant(&'a Variant)

An enum variant.

Field(&'a Field)

A field of a struct or an enum variant.

ImplItem(&'a ImplItem)

An item within an impl block.
