Struct OptionalTrailingBool 

Source 
pub struct OptionalTrailingBool<const DEFAULT: bool>;
Available on crate feature wincode only.
Expand description

A wincode schema for a bool that may be absent from the end of the wire payload. On write, the byte is always emitted. On read, an exhausted reader yields DEFAULT.
