Enum nix::fcntl::FlockArg

#[non_exhaustive]
pub enum FlockArg {
    LockShared,
    LockExclusive,
    Unlock,
    LockSharedNonblock,
    LockExclusiveNonblock,
    UnlockNonblock,
}

Operations for use with Flock::lock.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LockShared

shared file lock

LockExclusive

exclusive file lock

Unlock

Unlock file

LockSharedNonblock

Shared lock. Do not block when locking.

LockExclusiveNonblock

Exclusive lock. Do not block when locking.

UnlockNonblock

👎Deprecated since 0.28.0: Use FlockArg::Unlock instead

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

Formats the value using the given formatter.

impl Hash for FlockArg

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

Feeds this value into the given Hasher.

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

impl PartialEq for FlockArg

fn eq(&self, other: &FlockArg) -> 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.
