Enum syn::Meta
[−]
[src]
pub enum Meta {
Word(Ident),
List(MetaList),
NameValue(MetaNameValue),
}Content of a compile-time structured attribute.
This type is available if Syn is built with the "derive" or "full"
feature.
Word
A meta word is like the test in #[test].
List
A meta list is like the derive(Copy) in #[derive(Copy)].
NameValue
A name-value meta is like the path = "..." in #[path = "sys/windows.rs"].
Syntax tree enum
This type is a syntax tree enum.
Variants
Word(Ident)List(MetaList)A structured list within an attribute, like derive(Copy, Clone).
This type is available if Syn is built with the "derive" or
"full" feature.
NameValue(MetaNameValue)A name-value pair within an attribute, like feature = "nightly".
This type is available if Syn is built with the "derive" or
"full" feature.
Methods
impl Meta[src]
pub fn name(&self) -> Ident[src]
Returns the identifier that begins this structured meta item.
For example this would return the test in #[test], the derive in
#[derive(Copy)], and the path in #[path = "sys/windows.rs"].
