pub struct ExpnInfo {
pub call_site: Span,
pub callee: NameAndSpan,
}
Extra information for tracking macro expansion of spans
Fields
call_site | The location of the actual macro invocation, e.g. let x =
foo!();
This may recursively refer to other macro invocations, e.g. if
foo!() invoked bar!() internally, and there was an
expression inside bar! ; the call_site of the expression in
the expansion would point to the bar! invocation; that
call_site span would have its own ExpnInfo, with the call_site
pointing to the foo! invocation.
|
callee | Information about the macro and its definition.
The callee of the inner expression in the call_site
example would point to the macro_rules! bar { ... } and that
of the bar!() invocation would point to the macro_rules!
foo { ... } .

Search tricks
Prefix searches with a type followed by a colon (e.g.
fn:
) to restrict the search to a given type.
Accepted types are: fn
, mod
,
struct
, enum
,
trait
, typedef
(or
tdef
).
