Enum FileSeal

pub enum FileSeal {
    SealShrink,
    SealGrow,
    SealWrite,
    SealSeal,
    SealFutureWrite,
}

Seal that can be applied to a Memfd.

Variants

SealShrink

File cannot be reduced in size.

Corresponds to F_SEAL_SHRINK.

SealGrow

File cannot be grown in size.

Corresponds to F_SEAL_GROW.

SealWrite

File cannot be written.

Corresponds to F_SEAL_WRITE.

SealSeal

File sealing cannot be further manipulated.

Corresponds to F_SEAL_SEAL.

SealFutureWrite

Like F_SEAL_WRITE, but may still be written to through pre-existing writeable mappings. Introduced in Linux 5.1.

Corresponds to F_SEAL_FUTURE_WRITE.

Trait Implementations

impl Clone for FileSeal

fn clone(&self) -> FileSeal

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FileSeal

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for FileSeal

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FileSeal

fn eq(&self, other: &FileSeal) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
