CollectionError

A rejected collection operation. Encoding, validation and capacity errors precede writes; backing panics still follow the host’s failure contract.

Variants

Codec(CodecError)

Application encoding or declared size is invalid.

Corrupt(&'static str)

The persisted record or collection structure is invalid.

Format

The bytes belong to another format.

Checksum

Record integrity verification failed.

Budget

A record, arithmetic operation or allocation exceeds its resource budget.

Growth

Capacity could not be reserved.

NotEmpty

Creation was attempted in nonempty memory.

Poisoned

A prior backing failure prevents further access through this owner.

Bounds

An index or range is invalid.

Wire(Error)

Bounded Wire encoding or decoding failed.

Cell(StableCellPayloadError)

Cell envelope admission failed before reading its payload.

impl Eq for CollectionError

impl Error for CollectionError

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
