Enum MvStoreError 

pub enum MvStoreError {
    NotCommitted,
    PreviousAlreadyCapped {
        existing: u64,
    },
    PreviousCappedByInFlight,
    NonMonotonicBegin {
        prev: u64,
        new: u64,
    },
}

Errors returned by mutating MvStore operations. Read-side calls (read, visible_at) don’t error.

Variants

NotCommitted

push_committed got a version whose begin is an in-flight TxId rather than a committed Timestamp.

PreviousAlreadyCapped

The previous latest version is already capped at a different timestamp. Either the caller is double-committing, or the commit path is racing with itself (which 11.4’s commit-validation loop is supposed to prevent).

Fields

existing: u64

PreviousCappedByInFlight

The previous latest’s end is set to an in-flight cap. v0 rejects rather than silently overwriting; 11.4’s commit validation runs first so this shouldn’t fire in production.

NonMonotonicBegin

New version’s begin is not strictly greater than the previous latest’s begin. The clock should always hand out monotonically increasing timestamps; this is a corruption / bug indicator.

Fields

prev: u64

new: u64

Trait Implementations

impl Debug for MvStoreError

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

Formats the value using the given formatter.

impl Display for MvStoreError

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

Formats the value using the given formatter.

impl Error for MvStoreError

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 MvStoreError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
