# `IgniterCss.Validation`
[🔗](https://github.com/ash-project/igniter_css/blob/v1.1.2/lib/igniter_css/structs.ex#L106)

Whether a stylesheet is understood well enough to patch.

`round_trips` is the half that matters for safety: it is what every codemod
checks before touching a file. A stylesheet that round-trips but has
diagnostics is still patchable; one that does not round-trip is not, and
`IgniterCss` will refuse rather than risk a wrong edit.

`errors` is the verdict, each placed by line and column: the parser's errors
less the ones it raises against valid CSS, such as a `:` in a custom
property's value or an `@apply` with no `;` written last in a block.
`diagnostics` counts what the parser raised before that.

# `t`

```elixir
@type t() :: %IgniterCss.Validation{
  diagnostics: non_neg_integer(),
  errors: [IgniterCss.Diagnostic.t()],
  message: String.t(),
  round_trips: boolean(),
  valid: boolean()
}
```
