Struct ShapeGuard 

pub struct ShapeGuard { /* private fields */ }

A backend-neutral symbolic-shape obligation.

Implementations

impl ShapeGuard

pub fn new(relation: ProgramShapeRelation, lhs: DimExpr, rhs: DimExpr) -> Self

Construct a shape guard.

pub const fn relation(&self) -> ProgramShapeRelation

Return the required relation.

pub const fn lhs(&self) -> &DimExpr

Borrow the left expression.

pub const fn rhs(&self) -> &DimExpr

Borrow the right expression.

pub const fn source_family(&self) -> Option<&'static str>

Return the diagnostic family that introduced this guard, when known.

Diagnostic provenance does not participate in semantic equality or the semantic fingerprint.

Trait Implementations

impl Clone for ShapeGuard

fn clone(&self) -> ShapeGuard

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeGuard

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

Formats the value using the given formatter.

impl Hash for ShapeGuard

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 ShapeGuard

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