Tracking Issue for future-incompatibility lint out_of_scope_macro_calls #144406
Description
The out_of_scope_macro_calls lint detects macro_rules called when they are not in scope,
above their definition, which may happen in key-value attributes.
Example
#![doc = in_root!()]
macro_rules! in_root { () => { "" } }
fn main() {}Explanation
The scope in which a macro_rules item is visible starts at that item and continues
below it. This is more similar to let than to other items, which are in scope both above
and below their definition.
Due to a bug macro_rules were accidentally in scope inside some key-value attributes
above their definition. The lint catches such cases.
To address the issue turn the macro_rules into a regularly scoped item by importing it
with use.
Implementation history
- ast: Standardize visiting order for attributes and node IDs #125741 introduced the lint
- out_of_scope_macro_calls: Detect calls inside attributes more precisely #126987 fixed some positives
- Ensure
out_of_scope_macro_callslint is registered #127191 integrated it into the allow/warn/deny infrastructure - Mark all deprecation lints in name resolution as deny-by-default and report-in-deps #143929 made the lint deny-by-default and report-in-deps
- resolve: When suppressing
out_of_scope_macro_callssuppressunused_importsas well #147914 avoided an undesirableunused_importswarning - XXX turned the lint into a hard error
