Macro std::column 1.0.0
[−]
[src]
macro_rules! column { () => { ... }; }
A macro which expands to the column number on which it was invoked.
The expanded expression has type u32
, and the returned column is not
the invocation of the column!()
macro itself, but rather the first macro
invocation leading up to the invocation of the column!()
macro.
Examples
let current_col = column!(); println!("defined on column: {}", current_col);Run
