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 Constraint

fn cmp(&self, other: &Constraint) -> 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 ParseOp for Constraint

fn parse_op( &self, bytes: &mut impl Iterator<Item = u8>, ) -> Result<Self::Op, Self::Error>

Attempt to parse the operation associated with the opcode from the given bytes.

Only consumes the bytes necessary to construct any associated data.

Returns an error in the case that the given bytes iterator contains insufficient bytes to parse the op.

type Op = Constraint

The operation associated with the opcode.

type Error = NotEnoughBytesError

Any error that might occur while parsing.

impl PartialEq for Constraint

fn eq(&self, other: &Constraint) -> 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 Constraint

fn partial_cmp(&self, other: &Constraint) -> 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 TryFrom<u8> for Constraint

type Error = InvalidOpcodeError

The type returned in the event of a conversion error.

fn try_from(u: u8) -> Result<Self, Self::Error>

Performs the conversion.
