Enum PersistentHnswError 

pub enum PersistentHnswError {
    Io(Error),
    Decode(Box<ErrorKind>),
}

Errors surfaced by PersistentHnsw. Hand-rolled (no thiserror) because that crate is gated behind the audio feature in aprender-core/Cargo.toml; promoting it for one error type is more dep-tree churn than the two manual impls below.

Variants

Io(Error)

I/O failure while reading or writing the snapshot file.

Decode(Box<ErrorKind>)

bincode encode/decode failure. Usually means the snapshot was produced by an incompatible version of the type or got truncated mid-write. Phase 2 (FALSIFY-HNSW-PERSIST-002) will guarantee that a clean error here, not silent corruption, is what callers see for any partial-write scenario.

Trait Implementations

impl Debug for PersistentHnswError

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

Formats the value using the given formatter.

impl Display for PersistentHnswError

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

Formats the value using the given formatter.

impl Error for PersistentHnswError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Box<ErrorKind>> for PersistentHnswError

fn from(e: Box<ErrorKind>) -> PersistentHnswError

Converts to this type from the input type.

impl From<Error> for PersistentHnswError

fn from(e: Error) -> PersistentHnswError
