Struct ArrayWitness

pub struct ArrayWitness { /* private fields */ }

A Vec-based implementation of Witness with no special logic.

Example

use sov_state::{ArrayWitness, Witness};

let witness = ArrayWitness::default();

witness.add_hint(1u64);
witness.add_hint(2u64);

assert_eq!(witness.get_hint::<u64>(), 1u64);
assert_eq!(witness.get_hint::<u64>(), 2u64);

Trait Implementations

impl Debug for ArrayWitness

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

Formats the value using the given formatter.

impl Default for ArrayWitness

fn default() -> ArrayWitness

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ArrayWitness

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ArrayWitness

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Witness for ArrayWitness

fn add_hint<T: BorshSerialize>(&self, hint: T)

Adds a serializable “hint” to the witness value, which can be later read by the zkVM circuit.

fn get_hint<T: BorshDeserialize>(&self) -> T

Retrieves a “hint” from the witness value.

fn merge(&self, rhs: &Self)

Adds all hints from rhs to self.
