Struct syntax::ext::hygiene::NameAndSpan [−][src]
pub struct NameAndSpan { pub format: ExpnFormat, pub allow_internal_unstable: bool, pub allow_internal_unsafe: 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.
