Enum StoreError 

pub enum StoreError {
    Io {
        op: &'static str,
        path: PathBuf,
        message: String,
    },
    MissingPayload {
        hash: BlockHash,
    },
}

Something went wrong reaching the disk tier. Corruption and incompatibility are not here: those are misses, reported through DiskStats, because a caller’s only sane response to either is to recompute the prefix.

Variants

Io

Fields

op: &'static str

path: PathBuf

message: String

MissingPayload

The index named a block whose payload is nowhere: not on disk, not in the write buffer. This is not a cache miss – it is the write-ordering invariant (buffer -> index -> queue) having been violated, i.e. a bug in this module, and it is surfaced rather than smoothed into a miss so a test can fail on it.

Fields

hash: BlockHash

Trait Implementations

impl Clone for StoreError

fn clone(&self) -> StoreError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Eq for StoreError

impl Error for StoreError

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 PartialEq for StoreError

fn eq(&self, other: &StoreError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
