Struct Action 

pub struct Action<A> { /* private fields */ }

An action applied to the global ledger.

This both creates a note (adding a commitment to the global ledger), and consumes some note created prior to this action (adding a nullifier to the global ledger).

Implementations

impl<T> Action<T>

pub fn from_parts( nf: Nullifier, rk: VerificationKey<SpendAuth>, cmx: ExtractedNoteCommitment, encrypted_note: TransmittedNoteCiphertext, cv_net: ValueCommitment, authorization: T, ) -> Self

Constructs an Action from its constituent parts.

pub fn nullifier(&self) -> &Nullifier

Returns the nullifier of the note being spent.

pub fn rk(&self) -> &VerificationKey<SpendAuth>

Returns the randomized verification key for the note being spent.

pub fn cmx(&self) -> &ExtractedNoteCommitment

Returns the commitment to the new note being created.

pub fn encrypted_note(&self) -> &TransmittedNoteCiphertext

Returns the encrypted note ciphertext.

pub fn rho(&self) -> Rho

Obtains the Rho value that was used to construct the new note being created.

pub fn cv_net(&self) -> &ValueCommitment

Returns the commitment to the net value created or consumed by this action.

pub fn authorization(&self) -> &T

Returns the authorization for this action.

pub fn map<U>(self, step: impl FnOnce(T) -> U) -> Action<U>

Transitions this action from one authorization state to another.

pub fn try_map<U, E>( self, step: impl FnOnce(T) -> Result<U, E>, ) -> Result<Action<U>, E>

Transitions this action from one authorization state to another.

impl<T> Action<T>

pub fn to_instance(&self, flags: Flags, anchor: Anchor) -> Instance

Available on crate feature circuit only.

Prepares the public instance for this action, for creating and verifying the bundle proof.

Trait Implementations

impl<A: Clone> Clone for Action<A>

fn clone(&self) -> Action<A>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<A: Debug> Debug for Action<A>

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

Formats the value using the given formatter.

impl DynamicUsage for Action<Signature<SpendAuth>>

fn dynamic_usage(&self) -> usize

Returns a best estimate of the amount of heap-allocated memory used by this type.

fn dynamic_usage_bounds(&self) -> (usize, Option<usize>)

Returns the lower and upper bounds on the amount of heap-allocated memory used by this type.

impl<T> From<&Action<T>> for CompactAction

fn from(action: &Action<T>) -> Self

Converts to this type from the input type.

impl<T> ShieldedOutput<OrchardDomain, ENC_CIPHERTEXT_SIZE> for Action<T>

fn ephemeral_key(&self) -> EphemeralKeyBytes

Exposes the ephemeral_key field of the output.

fn cmstar_bytes(&self) -> [u8; 32]

Exposes the cmu_bytes or cmx_bytes field of the output.

fn enc_ciphertext(&self) -> &[u8; 580]

Exposes the note ciphertext of the output.
