This directory contains snippets of code that should yield a warning/note/help/error at compilation. Syntax of annotations is described in rust documentation. For more information check out
To run compile tests issue
cargo +nightly --test --features compiletest.
compiletestcrate cannot deal with the fact that macro invocations effectively changes line numbering. To prevent this add a
// error-pattern:<your error message here>on the top of the file and make sure that you set
denylint level if you want to test compiler message different than error.
compiletestcrate by default sets
allow(dead_code)lint level so make sure that you change it to something suiting your needs even if the warning is issued prior to any macro invocation.
error: 0 unexpected errors found, 1 expected errors not founddespite the fact that some error was bound to occur don‘t worry - it’s a known issue in the
compiletestcrate and your error was probably not registered - make sure that your annotations are correct and that you are setting correct lint levels.
