Struct macrotk_core::meta::MetaList[−][src]

pub struct MetaList {
    pub name: Option<Path>,
    pub paren: Option<Paren>,
    pub list: Punctuated<MetaValue, Comma>,
}
Expand description

A meta list.

Use this as the “entrypoint” of your attribute proc macro.

Fields

name: Option<Path>
Expand description

Can be None if this is the root list.

paren: Option<Paren>
Expand description

Can be None if this is the root list.

list: Punctuated<MetaValue, Comma>

Implementations

impl MetaList[src]

pub fn get<T>(&self, name: &str) -> Option<Result<T, Error>> where
    T: FromMeta, [src]

Gets a type by name.

This considers both list types (MetaList) and name-value pairs (MetaNameValue).

pub fn parse_root_attr(p: ParseStream<'_>) -> Result<MetaList, Error>[src]
