source · [−]

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

Available on Android or Linux only.

Expand description

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.
