Struct NotPinned 

pub struct NotPinned {
    pub what: String,
    pub reference: String,
    pub defect: PinDefect,
}

An image reference that is not pinned by a sha256 digest, and why not.

Carries what because which setting to go and change is half of any message a reader can act on, and PinDefect because what is wrong with the reference is the other half. It used to carry only the first and assert the second, which is the defect PinDefect documents.

Its audience is deliberately stated wide: anyone who wrote a reference this module will not accept, including people who have already pinned. The previous doc comment said this was “a message met by people who have only ever typed a tag” — a type narrowing its own audience and then being used for a wider one, which is how the wrong sentence stayed comfortable for three of its four callers.

Fields

what: String

What wanted the image, so the reader knows which setting to change.

reference: String

The reference as it was written.

defect: PinDefect

What is wrong with it, which selects both the sentence and the guidance.

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
