Struct tuxedo_core::verifier::Sr25519Signature

pub struct Sr25519Signature {
    pub owner_pubkey: H256,
}

Require a signature from the private key corresponding to the given public key. This is the simplest way to require a signature. If you prefer not to expose the public key until spend time, use P2PKH instead.

Uses the Sr25519 signature scheme and Substrate’s host functions.

Fields

owner_pubkey: H256

Implementations

impl Sr25519Signature

pub fn new<T: Into<H256>>(owner_pubkey: T) -> Self

Create a new instance that requires a signature from the given public key

Trait Implementations

impl Clone for Sr25519Signature

fn clone(&self) -> Sr25519Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sr25519Signature

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

Formats the value using the given formatter.

impl Decode for Sr25519Signature

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self> ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<'de> Deserialize<'de> for Sr25519Signature

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for Sr25519Signature

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

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

Convert self to an owned vector.

fn using_encoded<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback ) -> __CodecOutputReturn

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl PartialEq for Sr25519Signature

fn eq(&self, other: &Sr25519Signature) -> bool

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Sr25519Signature

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeInfo for Sr25519Signature

type Identity = Sr25519Signature

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl Verifier for Sr25519Signature

type Redeemer = CryptoBytes<sp_core::::sr25519::Signature::{constant#0}, (SignatureTag, Sr25519Tag)>

The type that will be supplied to satisfy the verifier and redeem the UTXO.

fn verify(&self, simplified_tx: &[u8], _: u32, sig: &Signature) -> bool

Main function in the trait. Does the checks to make sure an output can be spent.

fn new_unspendable() -> Option<Self>

A way to create a new instance of the verifier whose semantics cannot be spent. This may be a signature check with a pubkey of 0 or a hashlock with a hash o 0 or a bitcoin script that directly returns false, etc.
