Struct focus_chain_provider::FocusChainProviderPublisher

source · 
pub struct FocusChainProviderPublisher { /* private fields */ }
Expand description

Allows new focus chain values to be stored for transmission to watcher clients (through the corresponding FocusChainProviderRequestStreamHandler).

Instantiate using make_publisher_and_stream_handler().

Implementations§

source§

impl FocusChainProviderPublisher

source

pub fn set_state_and_notify_if_changed<C: FocusChainExt>( &self, new_state: &C ) -> Result<(), Status>

Updates the focus chain. If the new value is different from the previous value, sends an update to all listeners.

Returns an error if there are any problems with duplicating the FocusChain.

source

pub fn set_state_and_notify_always<C: FocusChainExt>( &self, new_state: &C ) -> Result<(), Status>

Updates the focus chain. Sends an update to all listeners even if the value hasn’t changed.

Returns an error if there are any problems with duplicating the FocusChain.
