Flush deferred errors

Within a defer_errors block, flush any deferred errors, turning them into realised errors. If no deferrable errors have occurred, this function has no effect.

deferred_errors_flush()

Examples

check_positive <- function(x) {
  if (x < 0) {
    deferrable_error(paste("got a negative number:", x))
  }
}
err <- tryCatch(
  defer::defer_errors({
    check_positive(-1)
    defer::deferred_errors_flush()
    check_positive(-2)
  }),
  error = identity)
err
#> <deferred_errors: 1 error occured:
#>   - got a negative number: -1>
