Enum Error 

#[non_exhaustive]
pub enum Error {
    Storage(StorageError),
    Blob(BlobError),
    Config(ConfigError),
    Bundle(BundleError),
}

Top-level hh-core error.

#[non_exhaustive]: this and the other error enums below are expected to gain variants over time (this PR added StorageError::StillRecording); non-exhaustive keeps that additive under cargo-semver-checks --release-type minor instead of registering as a break — a downstream match must already carry a wildcard arm, matching CLAUDE.md’s v1.0.0 addendum (“additive changes … not breaking”).

Variants (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.

Storage(StorageError)

SQLite storage failure (IO, constraint, or migration).

Blob(BlobError)

Blob store failure (IO, compression, or hash mismatch).

Config(ConfigError)

Configuration parsing failure. Per SRS §4.2 config never fails to start the program on unknown keys (those warn); this is only raised for a malformed TOML file or a value that cannot be interpreted.

Bundle(BundleError)

Portable session bundle (hh export --bundle / hh import) build or parse failure.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎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
