Initializes a new Execution instance with the given transitions.

pub fn size_in_bytes(&self) -> Result<u64>

Returns the size in bytes.

pub const fn global_state_root(&self) -> N::StateRoot

Returns the global state root.

pub const fn proof(&self) -> Option<&Proof<N>>

Returns the proof.

pub fn to_execution_id(&self) -> Result<Field<N>>

Returns the execution ID.

impl<N: Network> Execution<N>

pub fn contains_transition(&self, transition_id: &N::TransitionID) -> bool

Returns true if the execution contains the transition for the given transition ID.

pub fn get_transition( &self, transition_id: &N::TransitionID, ) -> Option<&Transition<N>>

pub fn push(&mut self, transition: Transition<N>)

Appends the given Transition to the execution.

pub fn pop(&mut self) -> Result<Transition<N>>

Pops the last Transition from the execution.

pub fn len(&self) -> usize

Returns the number of transitions in the execution.

pub fn is_empty(&self) -> bool

Returns true if the execution is empty.

impl<N: Network> Execution<N>

pub fn into_transitions( self, ) -> impl ExactSizeIterator + DoubleEndedIterator<Item = Transition<N>>

Returns a consuming iterator over the underlying transitions.

pub fn transitions( &self, ) -> impl '_ + ExactSizeIterator + DoubleEndedIterator<Item = &Transition<N>>

Returns an iterator over the underlying transitions.

pub fn commitments(&self) -> impl '_ + Iterator<Item = &Field<N>>

Returns an iterator over the commitments.

Trait Implementations

impl<N: Clone + Network> Clone for Execution<N>

where N::TransitionID: Clone, N::StateRoot: Clone,

fn clone(&self) -> Execution<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N: Network> Debug for Execution<N>

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

Prints the execution as a JSON-string.

impl<N: Default + Network> Default for Execution<N>

where N::TransitionID: Default, N::StateRoot: Default,

fn default() -> Execution<N>

Returns the “default value” for a type.

impl<'de, N: Network> Deserialize<'de> for Execution<N>

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserializes the execution from a string or bytes.

impl<N: Network> Display for Execution<N>

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

Displays the execution as a JSON-string.

impl<N: Network> FromBytes for Execution<N>

fn read_le<R: Read>(reader: R) -> IoResult<Self>

Reads the execution from a buffer.

fn from_bytes_le(bytes: &[u8]) -> Result<Self, Error>

where Self: Sized,

Returns Self from a byte array in little-endian order.

impl<N: Network> FromStr for Execution<N>

fn from_str(execution: &str) -> Result<Self, Self::Err>

Initializes the execution from a JSON-string.

type Err = Error

The associated error which can be returned from parsing.

impl<N: PartialEq + Network> PartialEq for Execution<N>

where N::TransitionID: PartialEq, N::StateRoot: PartialEq,

fn eq(&self, other: &Execution<N>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serializes the execution into string or bytes.

impl<N: Network> ToBytes for Execution<N>
