Struct SemanticPlacementConstraint 

pub struct SemanticPlacementConstraint { /* private fields */ }

Backend-neutral placement requirement retained for runtime preparation.

Implementations

impl SemanticPlacementConstraint

pub const fn any() -> Self

Construct an unrestricted placement constraint.

pub const fn same_as_input(input: usize) -> Self

Require placement compatible with one operation input.

pub const fn kind(self) -> SemanticPlacementKind

Return the placement kind.

pub const fn input(self) -> Option<usize>

Return the referenced input index, when applicable.

Trait Implementations

impl Clone for SemanticPlacementConstraint

fn clone(&self) -> SemanticPlacementConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SemanticPlacementConstraint

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

Formats the value using the given formatter.

impl Hash for SemanticPlacementConstraint

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 SemanticPlacementConstraint

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