Struct bm::List

pub struct List<R: RootStatus, C: Construct>(_);

Binary merkle vector.

Methods

impl<R: RootStatus, C: Construct> List<R, C> where
    C::Value: From<usize> + Into<usize>, 

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

Get value at index.

pub fn set<DB: WriteBackend<Construct = C> + ?Sized>(
    &mut self,
    db: &mut DB,
    index: usize,
    value: C::Value
) -> Result<(), Error<DB::Error>>

Set value at index.

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

Push a new value to the vector.

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

Pop a value from the vector.

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

Deconstruct the vector into one single hash value, and leak only the hash value.

pub fn reconstruct<DB: WriteBackend<Construct = C> + ?Sized>(
    root: C::Value,
    db: &mut DB,
    max_len: Option<u64>
) -> Result<Self, Error<DB::Error>>

Reconstruct the vector from a single hash value.

impl<C: Construct> List<Owned, C> where
    C::Value: From<usize> + Into<usize>, 

pub fn create<DB: WriteBackend<Construct = C> + ?Sized>(
    db: &mut DB,
    max_len: Option<u64>
) -> Result<Self, Error<DB::Error>>

Create a new vector.
