Enum ValueLayoutError 

pub enum ValueLayoutError {
    ValueTooLarge(usize),
    UnknownFlag(u8),
    TruncatedPointer {
        got: usize,
    },
    Codec(ValueCodecError),
    Overflow(OverflowError),
}

Errors returned by encode and decode.

Variants

ValueTooLarge(usize)

Logical value length exceeds MAX_VALUE_SIZE.

UnknownFlag(u8)

Stored cell flag byte sets a reserved bit.

TruncatedPointer

Stored bytes ended before the expected pointer payload.

Fields

got: usize

Codec(ValueCodecError)

LZ4 decode failed.

Overflow(OverflowError)

Overflow chain operation failed.

Trait Implementations

impl Debug for ValueLayoutError

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

Formats the value using the given formatter.

impl Display for ValueLayoutError

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

Formats the value using the given formatter.

impl Error for ValueLayoutError

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.
