[−][src]Struct proc_macro2::Span
A region of source code, along with macro expansion information.
Methods
impl Span[src]
pub fn call_site() -> Span[src]
The span of the invocation of the current procedural macro.
Identifiers created with this span will be resolved as if they were written directly at the macro call location (call-site hygiene) and other code at the macro call site will be able to refer to them as well.
pub fn unwrap(self) -> Span[src]
Convert proc_macro2::Span to proc_macro::Span.
This method is available when building with a nightly compiler, or when building with rustc 1.29+ without semver exempt features.
Panics
Panics if called from outside of a procedural macro. Unlike
proc_macro2::Span, the proc_macro::Span type can only exist within
the context of a procedural macro invocation.
