Summary: Context: https://fb.workplace.com/groups/rust.language/permalink/3338940432821215/ This codemod replaces *all* dependencies on `//common/rust/renamed:futures-preview` with `fbsource//third-party/rust:futures-preview` and their uses in Rust code from `futures_preview::` to `futures::`. This does not introduce any collisions with `futures::` meaning 0.1 futures because D20168958 previously renamed all of those to `futures_old::` in crates that depend on *both* 0.1 and 0.3 futures. Codemod performed by: ``` rg \ --files-with-matches \ --type-add buck:TARGETS \ --type buck \ --glob '!/experimental' \ --regexp '(_|\b)rust(_|\b)' \ | sed 's,TARGETS$,:,' \ | xargs \ -x \ buck query "labels(srcs, rdeps(%Ss, //common/rust/renamed:futures-preview, 1))" \ | xargs sed -i 's,\bfutures_preview::,futures::,' rg \ --files-with-matches \ --type-add buck:TARGETS \ --type buck \ --glob '!/experimental' \ --regexp '(_|\b)rust(_|\b)' \ | xargs sed -i 's,//common/rust/renamed:futures-preview,fbsource//third-party/rust:futures-preview,' ``` Reviewed By: k21 Differential Revision: D20213432 fbshipit-source-id: 07ee643d350c5817cda1f43684d55084f8ac68a6
