Expand description
Expands to the file name in which it was invoked.
With line!
and column!
, these macros provide debugging information for
developers about the location within the source.
The expanded expression has type &'static str
, and the returned file
is not the invocation of the file!
macro itself, but rather the
first macro invocation leading up to the invocation of the file!
macro.
§Examples
let this_file = file!();
println!("defined in file: {this_file}");
