Struct ContextCell

pub struct ContextCell {
    pub type_id: &'static str,
    pub context_id: usize,
    pub offset: usize,
}

Pointer to the position of a cell at offset in an advice column within a Context of context_id.

Fields

type_id: &'static str

The unique string identifier of the virtual region that this cell belongs to.

context_id: usize

Identifier of the Context that this cell belongs to.

offset: usize

Relative offset of the cell within this Context advice column.

Implementations

impl ContextCell

pub fn new(type_id: &'static str, context_id: usize, offset: usize) -> Self

Creates a new ContextCell with the given type_id, context_id, and offset.

Warning: If you create your own Context in a new virtual region not provided by our libraries, you must ensure that the type_id: &str of the context is a globally unique identifier for the virtual region, distinct from the other type_id strings used to identify other virtual regions. We suggest that you either include your crate name as a prefix in the type_id or use module_path! to generate a prefix. In the future we will introduce a macro to check this uniqueness at compile time.

Trait Implementations

impl Clone for ContextCell

fn clone(&self) -> ContextCell

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContextCell

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

Formats the value using the given formatter.

impl Hash for ContextCell

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 ContextCell

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

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

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