defmodule GoogleApi.Spanner.V1.Model.Expr do
  @moduledoc """
  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.

  ## Attributes

  *   `description` (*type:* `String.t`, *default:* `nil`) - Optional. Description of the expression. This is a longer text which
      describes the expression, e.g. when hovered over it in a UI.
  *   `expression` (*type:* `String.t`, *default:* `nil`) - Textual representation of an expression in Common Expression Language
      syntax.
  *   `location` (*type:* `String.t`, *default:* `nil`) - Optional. String indicating the location of the expression for error
      reporting, e.g. a file name and a position in the file.
  *   `title` (*type:* `String.t`, *default:* `nil`) - Optional. Title for the expression, i.e. a short string describing
      its purpose. This can be used e.g. in UIs which allow to enter the
      expression.
