Struct ComputeResultsHeader

pub struct ComputeResultsHeader {
    pub round: u64,
    pub previous_hash: Hash,
    pub io_root: Option<Hash>,
    pub state_root: Option<Hash>,
    pub messages_hash: Option<Hash>,
    pub in_msgs_hash: Option<Hash>,
    pub in_msgs_count: u32,
}

The header of a computed batch output by a runtime. This header is a compressed representation (e.g., hashes instead of full content) of the actual results.

Note

This should be kept in sync with go/roothash/api/commitment/executor.go.

Fields

round: u64

Round number.

previous_hash: Hash

Hash of the previous block header this batch was computed against.

io_root: Option<Hash>

The I/O merkle root.

state_root: Option<Hash>

The root hash of the state after computing this batch.

messages_hash: Option<Hash>

Hash of messages sent from this batch.

in_msgs_hash: Option<Hash>

The hash of processed incoming messages.

in_msgs_count: u32

The number of processed incoming messages.

Implementations

impl ComputeResultsHeader

pub fn encoded_hash(&self) -> Hash

Returns a hash of an encoded header.

pub fn is_parent_of(&self, child: &Header) -> bool

Returns true iff the header is the parent of a child header.

Trait Implementations

impl Clone for ComputeResultsHeader

fn clone(&self) -> ComputeResultsHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ComputeResultsHeader

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

Formats the value using the given formatter.

impl Decode for ComputeResultsHeader

fn try_default() -> Result<Self, DecodeError>

Try to decode from a missing/null/undefined value.

fn try_from_cbor_value(value: Value) -> Result<Self, DecodeError>

Try to decode from a given CBOR value.

fn try_from_cbor_value_default(value: Value) -> Result<Self, DecodeError>

where Self: Sized,

Try to decode from a given CBOR value, calling try_default in case the value is null or undefined.

impl Default for ComputeResultsHeader

fn default() -> ComputeResultsHeader

Returns the “default value” for a type.

impl Encode for ComputeResultsHeader

fn into_cbor_value(self) -> Value

Encode the type into a CBOR Value.

fn is_empty(&self) -> bool

Whether the value is equal to the empty value for the type.

impl EncodeAsMap for ComputeResultsHeader

fn into_cbor_value_map(self) -> Value

where Self: Sized,

Encode the type into a CBOR Map.

fn into_cbor_map(self) -> Vec<(Value, Value)>

where Self: Sized,

Encode the type into a CBOR Map, returning the map items.

impl Hash for ComputeResultsHeader

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ComputeResultsHeader

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
