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

Implementations

Trait Implementations

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 Copy for Output

impl Debug for Output

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

Formats the value using the given formatter.

impl DefaultHashable for Output

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.

impl Eq for Output

impl From<Output> for OutputIdentifier

fn from(out: Output) -> Self

Performs the conversion.

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 Ord for Output

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

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

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.

fn elmt_size() -> Option<u16>

Size of each element if "fixed" size. Elements are "variable" size if None.

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 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 Serialize for Output

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

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
