Every failure mode of reading or writing a Graven buffer.

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.

OutOfBounds

A length, header or element extends past the end of the buffer.

Truncated

A field slot is only partially covered by the table’s fixed_len.

BadOffset

A pointer targets a position outside the buffer.

InvalidUtf8

A string is not valid UTF-8.

Missing

A field required by the reader’s schema is absent.

Fields

field: &'static str

DepthExceeded

verify exceeded its maximum nesting depth.

BudgetExceeded

verify exceeded its visited-bytes budget.

TooLarge

The message would exceed i32::MAX bytes.

BadMagic

The envelope does not start with the Graven magic bytes.

UnsupportedVersion(u8)

The envelope version is not supported by this reader.

BadHeader

The envelope header is malformed.

Incomplete

The input is shorter than the envelope needs; at least needed bytes are required.

Fields

needed: usize

SchemaMismatch

The envelope’s schema id differs from the one the reader expects.

Fields

expected: u64

found: u64

ChecksumMismatch

The envelope’s CRC32C does not match its payload.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for ValidateError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

impl Copy for Error

impl Eq for Error

impl StructuralPartialEq for Error
