Struct pallet_merkle::GroupTree

pub struct GroupTree {
    pub leaf_count: u32,
    pub max_leaves: u32,
    pub depth: u8,
    pub root_hash: ScalarData,
    pub edge_nodes: Vec<ScalarData>,
}

Essential data about the tree

It holds:

• Current state of the tree
• Data needed for the next insert into the tree
• Limits of the tree

Fields

leaf_count: u32

Current number of leaves in the tree

max_leaves: u32

Maximum allowed leaves in the tree

depth: u8

Depth of the tree

root_hash: ScalarData

Current root hash of the tree

edge_nodes: Vec<ScalarData>

Edge nodes needed for the next insert in the tree

Implementations

impl GroupTree

Trait Implementations

impl Clone for GroupTree

fn clone(&self) -> GroupTree

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GroupTree

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Decode for GroupTree

fn decode<__CodecInputEdqy: Input>(
    __codec_input_edqy: &mut __CodecInputEdqy
) -> Result<Self, Error>

Attempt to deserialise the value from input.

pub fn skip<I>(input: &mut I) -> Result<(), Error> where
    I: Input, 

Attempt to skip the encoded value from input.

pub fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for GroupTree

fn encode_to<__CodecOutputEdqy: Output + ?Sized>(
    &self,
    __codec_dest_edqy: &mut __CodecOutputEdqy
)

Convert self to a slice and append it to the destination.

pub fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

pub fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

pub fn using_encoded<R, F>(&self, f: F) -> R where
    F: FnOnce(&[u8]) -> R,
