Implementations

impl Signature

pub fn new<T>(value: &T, secret: &KeyPair) -> Self

where T: BcsSignable,

Computes a signature.

pub fn check<T>(&self, value: &T, author: PublicKey) -> Result<(), CryptoError>

where T: BcsSignable + Debug,

Checks a signature.

pub fn check_optional_signature<T>( signature: Option<&Self>, value: &T, author: &PublicKey, ) -> Result<(), CryptoError>

where T: BcsSignable + Debug,

Checks an optional signature.

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

where T: BcsSignable, I: IntoIterator<Item = (&'a PublicKey, &'a Signature)>,

Verifies a batch of signatures.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Signature

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Signature

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

Formats the value using the given formatter.

impl InputType for Signature

type RawValueType = Signature

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 Signature

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 Signature

fn eq(&self, other: &Signature) -> 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 Signature

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 Signature

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Signature

impl Eq for Signature

impl StructuralPartialEq for Signature
