Struct ExtendedErrorSyncExternalTransitionMessage 

Source 
pub struct ExtendedErrorSyncExternalTransitionMessage(/* private fields */);
Expand description

Validated wire message for one legal ExtendedError transition.

Implementations§

Source§

impl ExtendedErrorSyncExternalTransitionMessage

Source

pub const fn as_wire(&self) -> &FrontendMessage

Borrows the validated wire message.

Source

pub fn into_wire(self) -> FrontendMessage

Returns the validated wire message.

Source

pub fn try_map_wire( self, map: impl FnOnce(FrontendMessage) -> FrontendMessage, ) -> Result<Self, FrontendMessage>

Mutates or replaces the wire value while preserving this transition variant.

§Errors

Returns the replacement when it no longer denotes this phase transition.
