ThreadExtensionLease

Struct ThreadExtensionLease 

Source
pub struct ThreadExtensionLease { /* private fields */ }
Expand description

Owned extension lease used when the caller has no pre-existing handle.

Keeping this value alive pins both the thread header and the registry record, so current-thread helpers cannot return data that becomes stale immediately after their temporary lookup handle is dropped.

Implementations§

Source§

impl ThreadExtensionLease

Source

pub fn thread_id(&self) -> ThreadId

Source

pub const fn data(&self) -> usize
