Enum StateRead

pub enum StateRead {
    KeyRange,
    KeyRangeExtern,
}

Operations related to reading state.

Variants

KeyRange

0x80: KRNG

Read a range of values at each key from state starting at the key into memory starting at the given memory address.

The key is lexographically incremented for each value read. All keys are assumed to be the same length.

An [index, len] pair is written into memory for each value, followed by the values themselves. E.g. when reading values a and b, they will be laid out in memory from the given mem_addr as follows: [a_addr, a_len, b_addr, b_len, a_value, b_value]

Stack Input

[key_w0, ...key_wN, key_len, num_keys_to_read, mem_addr]

KeyRangeExtern

0x81: KREX

Read a range of values at each key from external state starting at the key into memory starting at the given memory address.

The key is lexographically incremented for each value read. All keys are assumed to be the same length.

The external state is at the ext address.

An [index, len] pair is written into memory for each value, followed by the values themselves. E.g. when reading values a and b, they will be laid out in memory from the given mem_addr as follows: [a_addr, a_len, b_addr, b_len, a_value, b_value]

Stack Input

[ext_w0, ext_w1, ext_w2, ext_w3, key_w0, ...key_wN, key_len, num_keys_to_read, mem_addr]

Trait Implementations

impl Clone for StateRead

fn clone(&self) -> StateRead

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StateRead

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

Formats the value using the given formatter.

impl From<StateRead> for Op

fn from(subgroup: StateRead) -> Self

Converts to this type from the input type.

impl Hash for StateRead

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 Ord for StateRead

fn cmp(&self, other: &StateRead) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for StateRead

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

impl PartialOrd for StateRead

fn partial_cmp(&self, other: &StateRead) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl ToBytes for StateRead

type Bytes = StateRead

The iterator yielding bytes.

fn to_bytes(&self) -> Self::Bytes

Convert the operation to its serialized form in bytes.

impl ToOpcode for StateRead

type Opcode = StateRead

The associated Opcode type.

fn to_opcode(&self) -> Self::Opcode

The opcode associated with this operation.

impl TryFromBytes for StateRead

type Error = FromBytesError

Represents any error that might occur while parsing an op from bytes.

fn try_from_bytes( bytes: &mut impl Iterator<Item = u8>, ) -> Option<Result<Self, Self::Error>>

Parse a single operation from the given iterator yielding bytes.
