Struct memfd::Memfd [−][src]
pub struct Memfd { /* fields omitted */ }An anonymous volatile file, with sealing capabilities.
Methods
impl Memfd[src]
impl Memfdpub fn try_from_file(fp: File) -> Either<Self, File>[src]
pub fn try_from_file(fp: File) -> Either<Self, File>Try to convert a File object into a Memfd.
This requires transferring ownership of the File.
If the underlying file-descriptor is compatible with
memfd/sealing, it returns a proper Memfd object,
otherwise it transfers back ownership of the original
File for further usage.
pub fn as_file(&self) -> &File[src]
pub fn as_file(&self) -> &FileReturn a File object for this memfd.
pub fn into_file(self) -> File[src]
pub fn into_file(self) -> FileConsume this Memfd, returning the underlying File.
pub fn seals(&self) -> Result<SealsHashSet>[src]
pub fn seals(&self) -> Result<SealsHashSet>Return the current set of seals.
pub fn add_seal(&self, seal: FileSeal) -> Result<()>[src]
pub fn add_seal(&self, seal: FileSeal) -> Result<()>Add a single seal to the existing set of seals.
pub fn add_seals(&self, seals: &SealsHashSet) -> Result<()>[src]
pub fn add_seals(&self, seals: &SealsHashSet) -> Result<()>Add some seals to the existing set of seals.
