Trait Implementations

impl<BlockHash: Clone> Clone for LeavesProof<BlockHash>

fn clone(&self) -> LeavesProof<BlockHash>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<BlockHash: Debug> Debug for LeavesProof<BlockHash>

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

Formats the value using the given formatter.

impl<'de, BlockHash> Deserialize<'de> for LeavesProof<BlockHash>where
    BlockHash: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<BlockHash: PartialEq> PartialEq<LeavesProof<BlockHash>> for LeavesProof<BlockHash>

fn eq(&self, other: &LeavesProof<BlockHash>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<BlockHash> Serialize for LeavesProof<BlockHash>where
    BlockHash: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.
