Initializes a new Execution instance with the given transitions.

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

Returns the size in bytes.

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

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

Returns the execution ID.

impl<N> Execution<N>where N: Network,

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

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

pub fn find_transition( &self, id: &<N as Network>::TransitionID ) -> Option<&Transition<N>>

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> Execution<N>where N: Network,

pub fn into_transitions(self) -> impl ExactSizeIterator + DoubleEndedIterator

Returns a consuming iterator over the underlying transitions.

Trait Implementations

impl<N> Clone for Execution<N>where N: Clone + Network, <N as Network>::TransitionID: Clone, <N as Network>::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> Debug for Execution<N>where N: Network,

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

Prints the execution as a JSON-string.

impl<N> Default for Execution<N>where N: Default + Network, <N as Network>::TransitionID: Default, <N as Network>::StateRoot: Default,

fn default() -> Execution<N>

Returns the “default value” for a type.

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

fn deserialize<D>( deserializer: D ) -> Result<Execution<N>, <D as Deserializer<'de>>::Error>where D: Deserializer<'de>,

Deserializes the execution from a string or bytes.

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

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

Displays the execution as a JSON-string.

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

fn read_le<R>(reader: R) -> Result<Execution<N>, Error>where R: Read,

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> FromStr for Execution<N>where N: Network,

fn from_str( execution: &str ) -> Result<Execution<N>, <Execution<N> as FromStr>::Err>

Initializes the execution from a JSON-string.

type Err = Error

The associated error which can be returned from parsing.

impl<N> PartialEq<Execution<N>> for Execution<N>where N: PartialEq<N> + Network, <N as Network>::TransitionID: PartialEq<<N as Network>::TransitionID>, <N as Network>::StateRoot: PartialEq<<N as Network>::StateRoot>,

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