  @moduledoc """
  Represents an expression text. Example: title: "User account presence" description: "Determines whether the request has a user account" expression: "size(request.user) > 0"

  ## Attributes

  *   `description` (*type:* `String.t()`) - An 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()`) - Textual representation of an expression in Common Expression Language syntax. The application context of the containing message determines which well-known feature set of CEL is supported.
  *   `location` (*type:* `String.t()`) - An 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()`) - An 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.
