Macro creusot_contracts::std::prelude::v1::file

macro_rules! file {
    () => { ... };
}

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}");
