Implementations
sourceimpl TryCurrentError
impl TryCurrentError
sourcepub fn is_missing_context(&self) -> bool
pub fn is_missing_context(&self) -> bool
Returns true if the call failed because there is currently no runtime in the Tokio context.
sourcepub fn is_thread_local_destroyed(&self) -> bool
pub fn is_thread_local_destroyed(&self) -> bool
Returns true if the call failed because the Tokio context thread-local had been destroyed. This can usually only happen if in the destructor of other thread-locals.
