Enum ExpressionWidth

pub enum ExpressionWidth {
    Unbounded,
    Bounded {
        width: usize,
    },
}

Specifies the maximum width of the expressions which will be constrained.

Unbounded Expressions are useful if you are eventually going to pass the ACIR into a proving system which supports R1CS.

Bounded Expressions are useful if you are eventually going to pass the ACIR into a proving system which supports PLONK, where arithmetic expressions have a finite fan-in.

Trait Implementations

impl Clone for ExpressionWidth

fn clone(&self) -> ExpressionWidth

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExpressionWidth

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

Formats the value using the given formatter.

impl Default for ExpressionWidth

fn default() -> ExpressionWidth

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ExpressionWidth

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ExpressionWidth

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 ExpressionWidth

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

Convert domain type T to protobuf representation R.

fn decode(value: &ExpressionWidth) -> Result<ExpressionWidth>

fn encode_some(value: &T) -> Option<R>

Encode a field as Some.

fn encode_vec<'a, I>(values: I) -> Vec<R>

where I: IntoIterator<Item = &'a T>, T: 'a,

Encode multiple values as a vector.

fn decode_wrap(value: &R, msg: &'static str) -> Result<T, Report>

fn decode_vec(values: &[R]) -> Result<Vec<T>, Report>

Decode multiple values into a vector.

fn decode_vec_wrap(values: &[R], msg: &'static str) -> Result<Vec<T>, Report>

fn decode_opt_wrap( value: &Option<R>, msg: &'static str, ) -> Result<Option<T>, Report>

Decode an optional field, attaching a field name to any errors. Return None if the field is missing.

fn serialize_to_vec(value: &T) -> Vec<u8>

where R: Message,

Encode a domain type to protobuf and serialize it to bytes.

fn deserialize_from_slice(buf: &[u8]) -> Result<T, Report>
