Struct FileLock 

pub struct FileLock(/* private fields */);

Nonblocking exclusive sidecar lock; drop releases it. All cooperating writers must lock the same path before checking and replacing data. OS files: across processes (Windows: an exclusive handle, Linux: flock); a mount without OS files: inside this process.

Implementations

impl FileLock

pub fn acquire(path: &str) -> Option<Self>

Open or create without truncating. None means busy, invalid path, refused or I/O failure.

Trait Implementations

impl Drop for FileLock

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
