Enum MetaArg 

pub enum MetaArg {
    Literal(Lit),
    Path(Path),
    NameValue(MetaArgNameValue),
}

Drop-in replacement for syn::NestedMeta, which allows to parse attributes which can have arguments made of either literal, path or MetaArgNameValue expressions.

Variants

Literal(Lit)

Attribute argument in form of literal

Path(Path)

Attribute argument in form of a path

NameValue(MetaArgNameValue)

Attribute argument in form of name = value expression, where value can be any ArgValue-representable data

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
