Struct ChunkStateTransition

pub struct ChunkStateTransition {
    pub block_hash: CryptoHash,
    pub base_state: PartialState,
    pub post_state_root: CryptoHash,
}

Represents the base state and the expected post-state-root of a chunk’s state transition. The actual state transition itself is not included here.

Fields

block_hash: CryptoHash

The block that contains the chunk; this identifies which part of the state transition we’re talking about.

base_state: PartialState

The partial state before the state transition. This includes whatever initial state that is necessary to compute the state transition for this chunk.

post_state_root: CryptoHash

The expected final state root after applying the state transition. This is redundant information, because the post state root can be derived by applying the state transition onto the base state, but this makes it easier to debug why a state witness may fail to validate.

Trait Implementations

impl BorshDeserialize for ChunkStateTransition

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for ChunkStateTransition

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for ChunkStateTransition

fn clone(&self) -> ChunkStateTransition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChunkStateTransition

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

Formats the value using the given formatter.

impl PartialEq for ChunkStateTransition

fn eq(&self, other: &ChunkStateTransition) -> 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.
