Struct BoardLock 

pub struct BoardLock { /* private fields */ }

Advisory RAII guard that serializes board writes.

The lock is acquired by opening .pinto/.lock and taking an OS-level exclusive lock. Unix and macOS use flock, while Windows uses LockFileEx; both locks are released by the kernel when the owner process terminates. If the file is already locked, acquisition retries until the wait limit is reached, then returns Error::Locked.

Serializing read-modify-write sequences (list/load → change → save) prevents concurrent CLI/TUI processes from losing updates. Read-only operations do not acquire this lock.

The PID written to the file is diagnostic text only and is never used to decide ownership. This avoids incorrectly reclaiming a lock when the recorded PID has been reused by another process.

Trait Implementations

impl Debug for BoardLock

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

Formats the value using the given formatter.

impl Drop for BoardLock

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.
