[−][src]Struct memfd::Memfd

pub struct Memfd { /* fields omitted */ }

An anonymous volatile file, with sealing capabilities.

Methods

impl Memfd[src]

pub fn try_from_file(fp: File) -> Either<Self, File>[src]

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]

Return a File object for this memfd.

pub fn into_file(self) -> File[src]

Consume this Memfd, returning the underlying File.

pub fn seals(&self) -> Result<SealsHashSet, Error>[src]

Return the current set of seals.

pub fn add_seal(&self, seal: FileSeal) -> Result<(), Error>[src]

Add a single seal to the existing set of seals.

pub fn add_seals(&self, seals: &SealsHashSet) -> Result<(), Error>[src]

Add some seals to the existing set of seals.
