Standard filesystem-only Yield. Every io-m2dir coroutine picks type Yield = M2dirYield.

Each variant is paired with the matching M2dirArg variant the driver feeds back on the next resume.

Variants

WantsPid

Driver must supply the current process id and feed back M2dirArg::Pid.

WantsRandom

Driver must supply len random bytes and feed back M2dirArg::Random.

Fields

len: usize

WantsFileExists(BTreeSet<M2dirPath>)

Driver must check each path for existence as a regular file and feed back M2dirArg::FileExists.

WantsDirRead(BTreeSet<M2dirPath>)

Driver must list each directory’s entries and feed back M2dirArg::DirRead.

WantsDirCreate(BTreeSet<M2dirPath>)

Driver must create each directory (with parents) and feed back M2dirArg::DirCreate.

WantsDirRemove(BTreeSet<M2dirPath>)

Driver must recursively remove each directory and feed back M2dirArg::DirRemove.

WantsFileRead(BTreeSet<M2dirPath>)

Driver must read each file’s bytes and feed back M2dirArg::FileRead.

WantsFileCreate(BTreeMap<M2dirPath, Vec<u8>>)

Driver must write each (path, bytes) pair and feed back M2dirArg::FileCreate.

WantsFileRemove(BTreeSet<M2dirPath>)

Driver must remove each file and feed back M2dirArg::FileRemove.

WantsRename(Vec<(M2dirPath, M2dirPath)>)

Driver must rename each (from, to) pair and feed back M2dirArg::Rename.
