Errors from local writer and durable store operations.

Downstream callers must allow for future variants:

use safemesh_crdt::local::LocalError;
fn classify(error: LocalError) -> &'static str {
    match error {
        LocalError::Refused => "refused",
        LocalError::Exhausted => "exhausted",
        LocalError::PeerWriterAhead => "writer ahead",
        LocalError::StoreExists => "store exists",
        LocalError::RecoveryRequired => "recovery",
        LocalError::UnsupportedFormat { .. } => "unsupported format",
        LocalError::Configuration => "configuration",
        LocalError::CounterWidth(_) => "counter width",
        LocalError::InvalidRecord(_) => "record",
        LocalError::History(_) => "history",
        LocalError::InvalidHistory => "invalid history",
        LocalError::Io(_) => "io",
        LocalError::AncestorSync { .. } => "ancestor sync",
        LocalError::RecordLimitExceeded { .. } => "record limit",
    }
}

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.

Refused

Exhausted

PeerWriterAhead

A peer supplied an own-writer record above the committed high-water.

StoreExists

A fresh writer store already exists at this root for this writer.

RecoveryRequired

Store metadata is damaged or disagrees with its durable history.

UnsupportedFormat

A stored wrapper has a version newer than this reader understands.

Fields

file: &'static str

version: u8

Configuration

CounterWidth(CoordinateError)

The requested counter width exceeds the core constructor domain.

InvalidRecord(WireError)

History(WireError)

InvalidHistory

Io(Error)

AncestorSync

First creation could not open or sync an ancestor; no fence is written.

Fields

path: PathBuf

source: Error

RecordLimitExceeded

A _with_limits restart found a committed history that declares more records than DecodeLimits::max_records. Checked from the frame header before any record is read; the store is unchanged.

Fields

max_records: usize

default_limit: bool
