Enum StoreError 

pub enum StoreError {
    Sqlite(Error),
    Json(Error),
    Time(ParseError),
    Io(Error),
    Core(CoreError),
    Validation(String),
    RowCountCheckedAddOverflow {
        table: &'static str,
        pre: u64,
        delta: u64,
    },
}

Errors raised by the SQLite store boundary.

Variants

Sqlite(Error)

SQLite operation failed.

Json(Error)

JSON encoding or decoding failed.

Time(ParseError)

Timestamp parsing failed.

Io(Error)

Filesystem operation failed.

Core(CoreError)

Core type validation failed.

Validation(String)

Store-specific validation failed.

RowCountCheckedAddOverflow

Post-migrate row-count verification refused because pre.events.checked_add(SCHEMA_V1_TO_V2_EVENT_BOUNDARY_DELTA) overflowed u64. A pre-migrate count at the saturation boundary is itself a bug; the verifier refuses honestly rather than masking the overflow with saturating_add. Surfaces stable invariant verify.row_counts.checked_add_overflow (RED_TEAM_FINDINGS phase B, finding B3).

Fields

table: &'static str

Counted table that overflowed (currently always events).

pre: u64

Pre-migrate row count from the backup manifest.

delta: u64

Documented v1 -> v2 boundary-append delta that triggered overflow.

Implementations

impl StoreError

pub fn invariant(&self) -> Option<&'static str>

Returns the stable invariant name for this error variant when one is defined. Stable invariant names are how operators and tests match on refusal classes without parsing free text.

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
