Struct syntax::ext::hygiene::NameAndSpan

pub struct NameAndSpan {
    pub format: ExpnFormat,
    pub allow_internal_unstable: bool,

    pub edition: Edition,
    pub span: Option<Span>,
}

Fields

format: ExpnFormat

The format with which the macro was invoked.

allow_internal_unstable: bool

Whether the macro is allowed to use #[unstable]/feature-gated features internally without forcing the whole crate to opt-in to them.

allow_internal_unsafe: bool

Whether the macro is allowed to use unsafe internally even if the user crate has #![forbid(unsafe_code)].

edition: Edition

Edition of the crate in which the macro is defined.

span: Option<Span>

The span of the macro definition itself. The macro may not have a sensible definition span (e.g. something defined completely inside libsyntax) in which case this is None.
