Struct Meta 

pub struct Meta {
    pub path: Path,
    pub args: Option<TokenStream>,
}

One META element: path or path(args).

Fields

path: Path

path of path(args).

args: Option<TokenStream>

The tokens inside the parentheses, if any.

Implementations

impl Meta

pub fn parse_args_with<P: Parser>(&self, parser: P) -> Result<P::Output>

Parses the args with parser.

pub fn kv(&self) -> Result<KvArgs>

The args as a KvArgs list. Absent args give an empty list.

pub fn name_values(&self) -> Result<Vec<MetaNameValue>>

The args as key = value pairs. Values must be expressions; use kv for types and lists.
