Struct Flag
pub struct Flag<B> { /* private fields */ }A defined flags value that may be named or unnamed.
Implementations
impl<B> Flag<B>
const fn new(name: &'static str, value: B) -> SelfDefine a flag.
If
nameis non-empty then the flag is named, otherwise it's unnamed.const fn name(&self) -> &'static strGet the name of this flag.
If the flag is unnamed then the returned string will be empty.
const fn value(&self) -> &BGet the flags value of this flag.
const fn is_named(&self) -> boolWhether the flag is named.
If
Flag::namereturns a non-empty string then this method will returntrue.const fn is_unnamed(&self) -> boolWhether the flag is unnamed.
If
Flag::namereturns a non-empty string then this method will returnfalse.
