Enum halo2_frontend::circuit::layouter::RegionColumn

pub enum RegionColumn {
    Column(Column<Any>),
    Selector(Selector),
}

The virtual column involved in a region. This includes concrete columns, as well as selectors that are not concrete columns at this stage.

Variants

Column(Column<Any>)

Concrete column

Selector(Selector)

Virtual column representing a (boolean) selector

Trait Implementations

impl Clone for RegionColumn

fn clone(&self) -> RegionColumn

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RegionColumn

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

Formats the value using the given formatter.

impl From<Column<Any>> for RegionColumn

fn from(column: Column<Any>) -> RegionColumn

Converts to this type from the input type.

impl From<Selector> for RegionColumn

fn from(selector: Selector) -> RegionColumn

Converts to this type from the input type.

impl Hash for RegionColumn

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 RegionColumn

fn cmp(&self, other: &Self) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for RegionColumn

fn eq(&self, other: &RegionColumn) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for RegionColumn

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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