pub struct WakeChain { /* private fields */ }

Ordered adapters with ids.

Implementations

impl WakeChain

pub fn new() -> WakeChain

Empty chain.

pub fn push(&mut self, id: &'static str, adapter: Box<dyn WakeAdapter>)

Appends a link.

pub fn prepend(&mut self, id: &'static str, adapter: Box<dyn WakeAdapter>)

Puts a link in front (an embedder’s own first stop, e.g. m4a’s letter hook).

pub fn ids(&self) -> Vec<&'static str>

Link ids in order.

pub fn is_empty(&self) -> bool

Whether the chain has no link.

pub fn best(&self, session: &ProviderSession) -> Option<&'static str>

First link whose probe passes, without waking.

pub fn wake( &mut self, session: &ProviderSession, letter: &WakeLetter<'_>, ) -> Result<(&'static str, WakeOutcome), ChainError>

Tries each link in order. The first Delivered or Queued wins.
