Validate (or coerce) the result of an ntrd_update_available() call

Source: R/extension_updates.R
validate_update_check_result.Rd

Accepts either an update_result S7 instance (the canonical form) or a plain list with the expected fields (a courtesy for extensions that haven't migrated to the constructor yet). Returns a validated update_result. On any error — wrong type, missing field, invalid value — emits a warning and returns the safe "no update available" default, i.e. update_result().

Usage

validate_update_check_result(x, package = NULL)

Arguments

x

Object to validate. Either an update_result or a list.

package

Optional package name, used only to make warning messages more informative.

Value

An update_result S7 object.

Details

This wrapper exists because extension authors write the function whose result this validates; the framework can never trust the value completely and must downgrade gracefully on malformed input.
