    f: F
) -> Result<Self, Error<DB::Error>> where
    F: FnOnce(Raw<Dangling, C>, &mut DB, usize) -> Result<S, Error<DB::Error>>, 

Reconstruct the mixed-length tree.

pub fn deconstruct<DB: ReadBackend<Construct = C> + ?Sized>(
    self,
    db: &mut DB
) -> Result<C::Value, Error<DB::Error>>

Deconstruct the mixed-length tree.

    &self,
    db: &mut DB,
    f: F
) -> Result<RT, Error<DB::Error>> where
    F: FnOnce(&S, &mut DB) -> Result<RT, Error<DB::Error>>, 

Call with the inner sequence.

pub fn with_mut<DB: WriteBackend<Construct = C> + ?Sized, RT, F>(
    &mut self,
    db: &mut DB,
    f: F
) -> Result<RT, Error<DB::Error>> where
    F: FnOnce(&mut S, &mut DB) -> Result<RT, Error<DB::Error>>, 

Call with a mutable reference to the inner sequence.

impl<C: Construct, S> LengthMixed<Owned, C, S> where
    S: Sequence<Construct = C, RootStatus = Dangling> + Leak,
    C::Value: From<usize> + Into<usize>,
