# A word of warning

|

Clippy works as a *plugin* to the compiler, which means using an unstable \
|
|
internal API. We have gotten quite good at keeping pace with the API \
|
|
evolution, but the consequence is that clippy absolutely needs to be compiled \
|
|
with the version of `rustc` it will run on, otherwise you will get strange \
|
|
errors of missing symbols.
