Trait NoArgsAttributeParser

pub(crate) trait NoArgsAttributeParser<S: Stage>: 'static {
    const PATH: &[Symbol];
    const ON_DUPLICATE: OnDuplicate<S>;
    const CREATE: fn(Span) -> AttributeKind;
}

An even simpler version of SingleAttributeParser: now automatically check that there are no arguments provided to the attribute.

WithoutArgs<T> where T: NoArgsAttributeParser implements SingleAttributeParser.

Required Associated Constants

const PATH: &[Symbol]

const ON_DUPLICATE: OnDuplicate<S>

const CREATE: fn(Span) -> AttributeKind

Create the AttributeKind given attribute’s Span.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
