Struct exonum::messages::SignedMessage

pub struct SignedMessage {
    pub payload: Vec<u8>,
    pub author: PublicKey,
    pub signature: Signature,
}

Protobuf-based container for an arbitrary signed message.

See module documentation for examples.

Fields

payload: Vec<u8>

Payload of the message.

author: PublicKey

PublicKey of the author of the message.

signature: Signature

Digital signature over payload created with the secret key of the author of the message.

Methods

impl SignedMessage

pub fn into_verified<T>(self) -> Result<Verified<T>> where
    T: TryFrom<Self>, 

Verifies message signature and returns the corresponding checked message.

impl SignedMessage

pub fn new(
    payload: impl BinaryValue,
    author: PublicKey,
    secret_key: &SecretKey
) -> Self

Creates a new signed message from the given binary value.

Trait Implementations

impl BinaryValue for SignedMessage

fn to_bytes(&self) -> Vec<u8>

Serializes the given value to the vector of bytes.

fn from_bytes(value: Cow<[u8]>) -> Result<Self, Error>

Deserializes the value from the given bytes array.

fn into_bytes(self) -> Vec<u8>

Consumes and serializes the given value to the vector of bytes. This method is faster with the wrapped values, thus if you wouldn't use value after serialization use it.

impl Clone for SignedMessage

fn clone(&self) -> SignedMessage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SignedMessage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SignedMessage

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

Deserialize this value from the given Serde deserializer.

impl Display for SignedMessage

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

Formats the value using the given formatter.

impl Eq for SignedMessage

impl<T> From<Verified<T>> for SignedMessage

fn from(msg: Verified<T>) -> Self

Performs the conversion.

impl FromHex for SignedMessage

type Error = Error

fn from_hex<T: AsRef<[u8]>>(v: T) -> Result<Self, Self::Error>

Creates an instance of type Self from the given hex string, or fails with a custom error type.

impl FromStr for SignedMessage

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl ObjectHash for SignedMessage

fn object_hash(&self) -> Hash

Returns a hash of the value.

impl Ord for SignedMessage

fn cmp(&self, other: &SignedMessage) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<SignedMessage> for SignedMessage

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

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

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

This method tests for !=.

impl PartialOrd<SignedMessage> for SignedMessage

fn partial_cmp(&self, other: &SignedMessage) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &SignedMessage) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &SignedMessage) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &SignedMessage) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &SignedMessage) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl ProtobufConvert for SignedMessage

type ProtoStruct = SignedMessage

Type generated from the Protobuf definition.

fn from_pb(pb: Self::ProtoStruct) -> Result<Self, Error>

Performs conversion from the type generated from Protobuf.

fn to_pb(&self) -> Self::ProtoStruct

Performs conversion to the type generated from Protobuf.

impl Serialize for SignedMessage

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

Serialize this value into the given Serde serializer.

impl StructuralEq for SignedMessage

impl StructuralPartialEq for SignedMessage

impl ToHex for SignedMessage

fn encode_hex<T: FromIterator<char>>(&self) -> T

Encode the hex strict representing self into the result.. Lower case letters are used (e.g. f9b4ca)

fn encode_hex_upper<T: FromIterator<char>>(&self) -> T

Encode the hex strict representing self into the result.. Lower case letters are used (e.g. F9B4CA)
