Enum DiffSizeError 

pub enum DiffSizeError {
    TooManyOps {
        got: usize,
        cap: usize,
    },
    Encoded {
        got: usize,
        cap: usize,
    },
}

Error returned by CapabilityDiff::try_to_bytes when the diff would exceed the wire-format caps the receiver enforces.

Senders that build diffs from peer-supplied or large-cardinality input MUST surface this error rather than swallow it. Without a sender-side cap, to_bytes would silently emit bytes that every peer’s from_bytes discarded — silent state divergence indistinguishable from a network drop.

Variants

TooManyOps

ops.len() exceeds MAX_DIFF_OPS. Detected before serialization so the sender pays no heap cost on rejection.

Fields

got: usize

Actual op count.

cap: usize

The cap, MAX_DIFF_OPS.

Encoded

Encoded byte length exceeds MAX_DIFF_BYTES. Surfaces either the actual encoded length (post-serialize) or a best-estimate from estimated_size() if the encoder itself failed.

Fields

got: usize

Actual or estimated encoded length in bytes.

cap: usize

The cap, MAX_DIFF_BYTES.

Trait Implementations

impl Clone for DiffSizeError

fn clone(&self) -> DiffSizeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiffSizeError

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

Formats the value using the given formatter.

impl Display for DiffSizeError

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

Formats the value using the given formatter.

impl Error for DiffSizeError

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 DiffSizeError

fn eq(&self, other: &DiffSizeError) -> 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.
