Modules§
- fd 🔒
- fd_list 🔒
- A very simple data structure for holding the FDs a WASI process is using. Keeps track of the first unused (i.e. freed) FD, which is slightly faster than doing a linear search of the entire array each time. Note, The Unix spec requires newly allocated FDs to always be the lowest-numbered FD available.
- inode_
guard 🔒 - notification 🔒
- path_
posix 🔒 - Guest POSIX path helpers.
Structs§

FdOutcome 🔒 - Result of removing an fd under
