Struct cedar_policy_core::ast::ExprShapeOnly

pub struct ExprShapeOnly<'a, T = ()>(_);

A new type wrapper around Expr that provides Eq and Hash implementations that ignore any source information or other generic data used to annotate the Expr.

Implementations

impl<'a, T> ExprShapeOnly<'a, T>

pub fn new(e: &'a Expr<T>) -> ExprShapeOnly<'a, T>

Construct an ExprShapeOnly from an Expr. The Expr is not modified, but any comparisons on the resulting ExprShapeOnly will ignore source information and generic data.

Trait Implementations

impl<'a, T: Clone> Clone for ExprShapeOnly<'a, T>

fn clone(&self) -> ExprShapeOnly<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug> Debug for ExprShapeOnly<'a, T>

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

Formats the value using the given formatter.

impl<'a, T> Hash for ExprShapeOnly<'a, T>

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<'a, T> PartialEq<ExprShapeOnly<'a, T>> for ExprShapeOnly<'a, T>

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