Implementations§

Source§

impl Flag

Source

pub const fn new() -> Flag

🔬This is a nightly-only experimental API. (sync_poison_mod #134646)
Source

pub fn borrow(&self) -> LockResult<()>

🔬This is a nightly-only experimental API. (sync_poison_mod #134646)

Checks the flag for an unguarded borrow, where we only care about existing poison.

Source

pub fn guard(&self) -> LockResult<Guard>

🔬This is a nightly-only experimental API. (sync_poison_mod #134646)

Checks the flag for a guarded borrow, where we may also set poison when done.

Source

pub fn done(&self, guard: &Guard)

🔬This is a nightly-only experimental API. (sync_poison_mod #134646)
Available on panic=unwind only.
Source

pub fn get(&self) -> bool

🔬This is a nightly-only experimental API. (sync_poison_mod #134646)
Available on panic=unwind only.
Source

pub fn clear(&self)

🔬This is a nightly-only experimental API. (sync_poison_mod #134646)
