Struct ColumnId

pub struct ColumnId { /* private fields */ }

Unique identifier for a column within a constraint system.

IDs are assigned when columns are added to the constraint system and remain stable when more columns are added.

Trait Implementations

impl Clone for ColumnId

fn clone(&self) -> ColumnId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnId

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

Formats the value using the given formatter.

impl<F: TowerField> Index<ColumnId> for Table<F>

type Output = ColumnInfo<F>

The returned type after indexing.

fn index(&self, index: ColumnId) -> &Self::Output

Performs the indexing (container[index]) operation.

impl Ord for ColumnId

fn cmp(&self, other: &ColumnId) -> 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 ColumnId

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

fn partial_cmp(&self, other: &ColumnId) -> 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.
