OverridesError

Enum OverridesError 

Source
#[non_exhaustive]
pub enum OverridesError { Io(Error), Decode(Error), FutureVersion(u32), }
Expand description

Error type returned by this module.

#[non_exhaustive]: shep-core is a published library and this enum is reachable from it, so a further failure shape must not break an out-of-tree consumer’s match (IR-20).

Wraps io::Error/serde_json::Error directly rather than stringifying them, matching crate::kv::KvError, so callers keep the underlying diagnostic through core::error::Error::source, at the cost, documented there too, of not deriving Clone/PartialEq/Eq (IR-19’s exception for variants wrapping io::Error).

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Io(Error)

The store could not be read, written, or replaced.

§

Decode(Error)

The store’s JSON could not be parsed.

Refused rather than repaired: this file is an operator’s live config and a partial read of it would silently drop overrides that are still on disk.

§

FutureVersion(u32)

The store on disk is a version this build does not understand; carries that version. Nothing was written.
