Struct vidi::util::flock::Lock

pub struct Lock<'a, T: FileLike>(&'a T);

Locks a file securely (requires lockf) Not reentrant on Linux. That is, even the same thread cannot acquire the same file twice. BUT if there are two copies of this software in the same process, those copies can both lock the same file. This can happen if two different versions of the library are used, for example.

Tuple Fields

0: &'a T

Implementations

impl<'a, T: FileLike> Lock<'a, T>

fn new_(file: &'a T, mode: LockBlock) -> Result<Self, NotAvailable>

pub fn new(file: &'a T) -> Result<Self, NotAvailable>

pub fn new_wait(file: &'a T) -> Result<Self, NotAvailable>

Waits only if another process is holding the lock.

Trait Implementations

impl<'a, T: FileLike> Drop for Lock<'a, T>

fn drop(&mut self)

Executes the destructor for this type.
