Struct tuxedo_core::verifier::Unspendable

pub struct Unspendable;

A simple verifier that allows no one to consume an output ever.

This is useful for UTXOs that are expected to only ever be consumed by evictions, such as inherents for example.

Trait Implementations

impl Clone for Unspendable

fn clone(&self) -> Unspendable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Unspendable

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

Formats the value using the given formatter.

impl Decode for Unspendable

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 Default for Unspendable

fn default() -> Unspendable

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Unspendable

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for Unspendable

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<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

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 Unspendable

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

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 Unspendable

type Identity = Unspendable

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl Verifier for Unspendable

type Redeemer = ()

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

fn verify(&self, _simplified_tx: &[u8], _: u32, _: &()) -> 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.
