Implementations

impl EvmSignature

pub fn new(prehash: CryptoHash, secret: &EvmSecretKey) -> Self

Computes a secp256k1 signature for prehash using the given secret.

pub fn sign_prehash(secret: &EvmSecretKey, prehash: CryptoHash) -> Self

Computes a signature from a prehash.

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

where T: BcsSignable<'de> + Debug,

Checks a signature.

pub fn check_with_recover<'de, T>( &self, value: &T, sender_address: [u8; 20], ) -> Result<EvmPublicKey, CryptoError>

where T: BcsSignable<'de> + Debug,

Checks a signature against a recovered public key.

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

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

Verifies a batch of signatures.

Returns an error on first failed signature.

pub fn as_bytes(&self) -> [u8; 65]

Returns the byte representation of the signature.

pub fn from_slice<A: AsRef<[u8]>>(bytes: A) -> Result<Self, CryptoError>

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

Trait Implementations

impl Clone for EvmSignature

fn clone(&self) -> EvmSignature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EvmSignature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EvmSignature

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EvmSignature

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

Formats the value using the given formatter.

impl FromStr for EvmSignature

type Err = CryptoError

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 InputType for EvmSignature

type RawValueType = EvmSignature

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<Value>) -> InputValueResult<Self>

Parse from Value. None represents undefined.

fn to_value(&self) -> Value

Convert to a Value for introspection.

fn as_raw_value(&self) -> Option<&Self::RawValueType>

Returns a reference to the raw value.

fn qualified_type_name() -> String

Qualified typename.

impl OutputType for EvmSignature

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, _: &ContextSelectionSet<'_>, _field: &Positioned<Field>, ) -> ServerResult<Value>

Resolve an output value to async_graphql::Value.

fn qualified_type_name() -> String

Qualified typename.

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

Introspection type name

impl PartialEq for EvmSignature

fn eq(&self, other: &EvmSignature) -> 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 ScalarType for EvmSignature

fn parse(value: Value) -> InputValueResult<Self>

Parse a scalar value.

fn to_value(&self) -> Value

Convert the scalar to Value.

fn is_valid(_value: &ConstValue) -> bool

Checks for a valid scalar value.

impl Serialize for EvmSignature

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

where S: Serializer,

Serialize this value into the given Serde serializer.
