Struct cedar_policy_core::ast::Unknown

pub struct Unknown {
    pub name: SmolStr,
    pub type_annotation: Option<Type>,
}

Representation of a partial-evaluation Unknown at the AST level

Fields

name: SmolStr

The name of the unknown

type_annotation: Option<Type>

The type of the values that can be substituted in for the unknown. If None, we have no type annotation, and thus a value of any type can be substituted.

Implementations

impl Unknown

pub fn new_untyped(name: impl Into<SmolStr>) -> Self

Create a new untyped Unknown

pub fn new_with_type(name: impl Into<SmolStr>, ty: Type) -> Self

Create a new Unknown with type annotation. (Only values of the given type can be substituted.)

Trait Implementations

impl Clone for Unknown

fn clone(&self) -> Unknown

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Unknown

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Unknown

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Unknown

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

Formats the value using the given formatter.

impl Hash for Unknown

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 Unknown

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

impl Serialize for Unknown

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Unknown
