Enum ChecksumError 

pub enum ChecksumError {
    CanonicalJsonFailed(Error),
    NonCanonicalContent {
        reason: String,
    },
}

Errors surfaced by checksum compute / verify.

Variants

CanonicalJsonFailed(Error)

serde_json rejected the frame body — typically a non-serializable payload (e.g. a Map with non-string keys, an f64::NAN).

NonCanonicalContent

Frame body contains content that cannot round-trip cross-impl through canonical JSON. Specifically: non-ASCII object keys (JS sorts by UTF-16 code-unit order; Rust BTreeMap sorts by UTF-8 byte order — these diverge for keys containing surrogate-pair code points), or subnormal f64 values (JS JSON.stringify and Rust serde_json via ryu may diverge on denormalized floats). Banned at the WAL encode boundary (B1 — option a) rather than allowed-with-silent-divergence.

Trait Implementations

impl Debug for ChecksumError

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

Formats the value using the given formatter.

impl Display for ChecksumError

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

Formats the value using the given formatter.

impl Error for ChecksumError

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<ChecksumError> for StorageError

Convenience: wal_frame_checksum / verify_wal_frame_checksum failures bubble through ? at the tier-flush boundary without explicit mapping. ChecksumError::CanonicalJsonFailed was a serde_json::Error at root, which is a codec-encode failure — funnel through the Codec variant. ChecksumError::NonCanonicalContent (B1, 2026-05-22) is a writer-side rejection of cross-impl-divergent content (non-ASCII keys, subnormal floats); also routed through Codec::Encode since it’s an encode-time failure surfaced from the same checksum codepath.

fn from(e: ChecksumError) -> Self

impl From<Error> for ChecksumError

fn from(source: Error) -> Self

Converts to this type from the input type.
