Implementations

impl Secp256k1Signature

pub fn new<'de, T>(value: &T, secret: &Secp256k1SecretKey) -> Secp256k1Signature

where T: BcsSignable<'de>,

Computes a secp256k1 signature for value using the given secret. It first serializes the T type and then creates the CryptoHash from the serialized bytes.

pub fn sign_prehash( secret: &Secp256k1SecretKey, prehash: CryptoHash, ) -> Secp256k1Signature

Computes a signature from a prehash.

pub fn check<'de, T>( &self, value: &T, author: Secp256k1PublicKey, ) -> Result<(), CryptoError>

where T: BcsSignable<'de> + Debug,

Checks a signature.

pub fn verify_batch<'a, 'de, T, I>( value: &'a T, votes: I, ) -> Result<(), CryptoError>

where T: BcsSignable<'de> + Debug, I: IntoIterator<Item = &'a (Secp256k1PublicKey, Secp256k1Signature)>,

Verifies a batch of signatures.

Returns an error on first failed signature.

pub fn as_bytes(&self) -> [u8; 64]

Returns the byte representation of the signature.

pub fn from_slice<A>(bytes: A) -> Result<Secp256k1Signature, CryptoError>

where A: AsRef<[u8]>,

Creates a signature from the bytes. Expects the signature to be serialized in raw-bytes form.

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

Performs copy-assignment from source.

impl Debug for Secp256k1Signature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Secp256k1Signature

fn deserialize<D>( deserializer: D, ) -> Result<Secp256k1Signature, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Secp256k1Signature

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

Formats the value using the given formatter.

impl InputType for Secp256k1Signature

type RawValueType = Secp256k1Signature

The raw type used for validator.

fn type_name() -> Cow<'static, str>

Type the name.

fn create_type_info(registry: &mut Registry) -> String

Create type information in the registry and return qualified typename.

fn parse( value: Option<ConstValue>, ) -> Result<Secp256k1Signature, InputValueError<Secp256k1Signature>>

Parse from Value. None represents undefined.

Convert to a Value for introspection.

fn as_raw_value( &self, ) -> Option<&<Secp256k1Signature as InputType>::RawValueType>

Returns a reference to the raw value.

fn qualified_type_name() -> String

Qualified typename.

impl OutputType for Secp256k1Signature

fn type_name() -> Cow<'static, str>

Type the name.

fn create_type_info(registry: &mut Registry) -> String

Create type information in the registry and return qualified typename.

async fn resolve( &self, _: &ContextBase<'_, &Positioned<SelectionSet>>, _field: &Positioned<Field>, ) -> Result<ConstValue, ServerError>

Resolve an output value to async_graphql::Value.

fn qualified_type_name() -> String

Qualified typename.

fn introspection_type_name(&self) -> Cow<'static, str>

impl PartialEq for Secp256k1Signature

fn eq(&self, other: &Secp256k1Signature) -> 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 Serialize for Secp256k1Signature

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

where S: Serializer,

Serialize this value into the given Serde serializer.
