Trait Implementations

impl Clone for MerkleTree

fn clone(&self) -> MerkleTree

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CommitEncode for MerkleTree

type CommitmentId = Commitment

Type of the resulting commitment.

fn commit_encode(&self, engine: &mut CommitEngine)

Encodes the data for the commitment by writing them directly into a std::io::Write writer instance

impl Conceal for MerkleTree

type Concealed = MerkleConcealed

The resulting confidential type concealing original data.

fn conceal(&self) -> Self::Concealed

Performs conceal procedure returning confidential data concealing original data.

impl Debug for MerkleTree

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

Formats the value using the given formatter.

impl From<&MerkleTree> for MerkleBlock

fn from(tree: &MerkleTree) -> Self

Converts to this type from the input type.

impl From<MerkleTree> for MerkleBlock

fn from(tree: MerkleTree) -> Self

Converts to this type from the input type.

impl Hash for MerkleTree

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MerkleTree

fn eq(&self, other: &MerkleTree) -> 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.

impl Proof for MerkleTree

fn matches(&self, other: &Self) -> bool

Verifies whether one MPC proof matches another MPC proof.

impl StrictDecode for MerkleTree

fn strict_decode(reader: &mut impl TypedRead) -> Result<Self, DecodeError>

fn strict_read(reader: impl ReadRaw) -> Result<Self, DecodeError>

impl StrictDumb for MerkleTree

fn strict_dumb() -> Self

impl StrictEncode for MerkleTree

fn strict_encode<W: TypedWrite>(&self, writer: W) -> Result<W>

fn strict_write(&self, writer: impl WriteRaw) -> Result<(), Error>

impl StrictStruct for MerkleTree

const ALL_FIELDS: &'static [&'static str]

fn strict_check_fields()

fn strict_type_info() -> TypeInfo<Self>

impl StrictType for MerkleTree

const STRICT_LIB_NAME: &'static str = LIB_NAME_COMMIT_VERIFY

fn strict_name() -> Option<TypeName>

impl TryCommitVerify<MultiSource, UntaggedProtocol> for MerkleTree

Panics

Panics if the crate is compiled without rand feature enabled and the MultiSource doesn’t contain a static entropy.

type Error = Error

Error type that may be reported during TryCommitVerify::try_commit.

fn try_commit(source: &MultiSource) -> Result<Self, Error>

Tries to create commitment to a byte representation of a given message.

fn verify(&self, msg: &Msg) -> Result<(), VerifyError>

Verifies the commitment against the message; default implementation just repeats the commitment to the message and check it against the self.

impl Eq for MerkleTree

impl StrictProduct for MerkleTree

impl StructuralPartialEq for MerkleTree
