public final class Expr extends com.google.protobuf.GeneratedMessageV3 implements ExprOrBuilder
 Represents a textual expression in the Common Expression Language (CEL)
 syntax. CEL is a C-like expression language. The syntax and semantics of CEL
 are documented at https://github.com/google/cel-spec.
 Example (Comparison):
     title: "Summary size limit"
     description: "Determines if a summary is less than 100 chars"
     expression: "document.summary.size() < 100"
 Example (Equality):
     title: "Requestor is owner"
     description: "Determines if requestor is the document owner"
     expression: "document.owner == request.auth.claims.email"
 Example (Logic):
     title: "Public documents"
     description: "Determine whether the document should be publicly visible"
     expression: "document.type != 'private' && document.type != 'internal'"
 Example (Data Manipulation):
     title: "Notification string"
     description: "Create a notification string with a timestamp."
     expression: "'New message received at ' + string(document.create_time)"
 The exact variables and functions that may be referenced within an expression
 are determined by the service that evaluates it. See the service
 documentation for additional information.
