Struct shm_fd::SharedFd

source · [−]

pub struct SharedFd { /* private fields */ }

Implementations

source

impl SharedFd

source

pub unsafe fn from_env() -> Option<Self>

Import a shared file descriptor based on environment variable SHM_SHARED_FDS.

Safety

Caller asserts that the environment variable has been set to a file descriptor that is not owned by any other resource.

source

pub fn into_file(self) -> Result<MemFile, Error>

Open the file descriptor.

This can fail if for some reason the file descriptor does not refer to an anonymous memory file.
