Methods

impl<R: RootStatus, DB: Backend, S> LengthMixed<R, DB, S> where
    S: Sequence<Backend = DB, RootStatus = Dangling>,
    EndOf<DB>: From<usize> + Into<usize>, 

pub fn reconstruct<F>(
    root: ValueOf<DB>,
    db: &DB,
    f: F
) -> Result<Self, Error<DB::Error>> where
    F: FnOnce(Raw<Dangling, DB>, &DB, usize) -> Result<S, Error<DB::Error>>, 

Reconstruct the mixed-length tree.

pub fn deconstruct(self, db: &DB) -> Result<ValueOf<DB>, Error<DB::Error>>

Deconstruct the mixed-length tree.

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

Call with the inner sequence.

pub fn with_mut<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<DB: Backend, S> LengthMixed<Owned, DB, S> where
    S: Sequence<Backend = DB, RootStatus = Dangling> + Leak,
    EndOf<DB>: From<usize> + Into<usize>, 

pub fn create<OS, F>(db: &mut DB, f: F) -> Result<Self, Error<DB::Error>> where
    F: FnOnce(&mut DB) -> Result<OS, Error<DB::Error>>,
    OS: Sequence<Backend = DB> + Leak<Metadata = S::Metadata>, 

Create a new mixed-length tree.
