Struct CopyOutCopyDataExternalTransitionMessage 

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

Validated wire message for one legal CopyOut transition.

Implementations§

Source§

impl CopyOutCopyDataExternalTransitionMessage

Source

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

Borrows the validated wire message.

Source

pub fn into_wire(self) -> BackendMessage

Returns the validated wire message.

Source

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

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

§Errors

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