Struct grin_core::core::transaction::Output

pub struct Output {
    pub features: OutputFeatures,
    pub commit: Commitment,
    pub proof: RangeProof,
}

Output for a transaction, defining the new ownership of coins that are being transferred. The commitment is a blinded value for the output while the range proof guarantees the commitment includes a positive value without overflow and the ownership of the private key.

Fields

features: OutputFeatures

Options for an output's structure or use

commit: Commitment

The homomorphic commitment representing the output amount

proof: RangeProof

A proof that the commitment is in the right range

Methods

impl Output

pub fn commitment(&self) -> Commitment

pub fn is_coinbase(&self) -> bool

Is this a coinbase kernel?

pub fn is_plain(&self) -> bool

Is this a plain kernel?

pub fn proof(&self) -> RangeProof

Range proof for the output

pub fn verify_proof(&self) -> Result<(), Error>

Validates the range proof using the commitment

pub fn batch_verify_proofs(
    commits: &Vec<Commitment>,
    proofs: &Vec<RangeProof>
) -> Result<(), Error>

Trait Implementations

impl DefaultHashable for Output

impl Writeable for Output

Implementation of Writeable for a transaction Output, defines how to write an Output as binary.

fn write<W: Writer>(&self, writer: &mut W) -> Result<(), Error>

Write the data held by this Writeable to the provided writer

impl Readable for Output

Implementation of Readable for a transaction Output, defines how to read an Output from a binary stream.

fn read(reader: &mut dyn Reader) -> Result<Output, Error>

Reads the data necessary to this Readable from the provided reader

impl PMMRable for Output

We can build an Output MMR but store instances of OutputIdentifier in the MMR data file.

type E = OutputIdentifier

The type of element actually stored in the MMR data file. This allows us to store Hash elements in the header MMR for variable size BlockHeaders.

fn as_elmt(&self) -> OutputIdentifier

Convert the pmmrable into the element to be stored in the MMR data file.

impl PartialOrd<Output> for Output

fn partial_cmp(&self, other: &Output) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl PartialEq<Output> for Output

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

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

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Copy for Output

impl Ord for Output

fn cmp(&self, other: &Output) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl Eq for Output

impl From<Output> for OutputIdentifier

fn from(out: Output) -> Self

Performs the conversion.

impl Clone for Output

fn clone(&self) -> Output

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Hash for Output

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Debug for Output

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

Formats the value using the given formatter.

impl Serialize for Output

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

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for Output

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.
