Implementations

impl TreeFeatureType

pub fn sum_length(&self) -> Option<u32>

Get length of encoded SummedMerk

pub fn is_sum_feature(&self) -> bool

Is sum feature?

Trait Implementations

impl Clone for TreeFeatureType

fn clone(&self) -> TreeFeatureType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TreeFeatureType

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

Formats the value using the given formatter.

impl Decode for TreeFeatureType

fn decode<R: Read>(input: R) -> Result<Self>

Reads bytes from the reader and returns the decoded value.

fn decode_into<R>(&mut self, input: R) -> Result<(), Error>

where R: Read,

Reads bytes from the reader and mutates self to the decoded value.

impl Encode for TreeFeatureType

fn encode_into<W: Write>(&self, dest: &mut W) -> Result<()>

Writes the encoded representation of the value to the destination writer. Can error due to either a write error from dest, or an encoding error for types where invalid values are possible.

fn encoding_length(&self) -> Result<usize>

Calculates the length of the encoding for this value. Can error for types where invalid values are possible.

fn encode(&self) -> Result<Vec<u8>, Error>

Returns the encoded representation of the value as a Vec<u8>.

impl PartialEq for TreeFeatureType

fn eq(&self, other: &TreeFeatureType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
