# Enum syn::MetaItem [−] [src]

    pub enum MetaItem {
        Word(Ident),
        List(Ident, Vec<NestedMetaItem>),
        NameValue(Ident, Lit),
    }

A compile-time attribute item.

E.g. `#[test]`, `#[derive(..)]` or `#[feature = "foo"]`

## Variants

`Word(Ident)`

Word meta item.

E.g. `test` as in `#[test]`

`List(Ident, Vec<NestedMetaItem>)`

List meta item.

E.g. `derive(..)` as in `#[derive(..)]`

`NameValue(Ident, Lit)`

Name-value meta item.

E.g. `feature = "foo"` as in `#[feature = "foo"]`

## Methods

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
