Represents the fundamental type categories in CEL.

This enum corresponds to the Kind type in CEL-CPP and serves as the base type classification system for CEL values and types. It provides a unified way to represent both value types and type kinds in the CEL type system.

Variants

Primitive Types

• Null - The null value type
• Bool - Boolean values
• Int - 64-bit signed integers

• Double - 64-bit floating-point numbers
• String - UTF-8 encoded strings
• Bytes - Raw byte sequences

Complex Types

• Struct - Structured data types
• List - Homogeneous lists
• Map - Key-value mappings

Protocol Buffer Types

• Duration - Time duration values
• Timestamp - Point-in-time values
• BoolWrapper - Protocol buffer bool wrapper

Special Types

• Unknown - Type not yet determined

fn clone(&self) -> Kind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Kind

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

Formats the value using the given formatter.

impl Display for Kind

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

Formats the value using the given formatter.

Either cxx::kind::Opaque or cxx::kind::Trivial.

impl From<Kind> for TypeKind

fn from(kind: Kind) -> Self

Converts to this type from the input type.

impl From<Kind> for ValueKind

fn from(kind: Kind) -> Self

Converts to this type from the input type.

impl From<TypeKind> for Kind

fn from(kind: TypeKind) -> Self

Converts to this type from the input type.
