Variants

OldVersion(String)

Occurs when a subtype is using a version format that is no longer accepted. This is mainly for recognizing when the Cryptographic types and signatures use old, no longer accepted algorithms.

SchemaMismatch

Occurs when a schema doesn’t match the document’s schema, a Schema was used when one isn’t specified by the document, or a NoSchema was used when a document specified a schema.

Fields of SchemaMismatch

actual: Option<Hash>expected: Option<Hash>

SerdeFail(String)

Occurs when serde serialization or deserialization fails

BadHeader(String)

Occurs when the header (compression marker and optional schema) failed to parse correctly.

FailDecompress(String)

Occurs when zstd compression fails, possibly due to a dictionary not being present in a schema, a checksum failing, or any of the other zstd failure modes.

LengthTooLong

Document/Entry/Query was greater than maximum allowed size on decode

Fields of LengthTooLong

max: usizeactual: usize

LengthTooShort

Document/Entry/Query ended too early.

Fields of LengthTooShort

step: &'static stractual: usizeexpected: usize

BadSignature

Signature attached to end of Document/Entry/Query didn’t validate

BadEncode(String)

Basic fog-pack encoding failure

FailValidate(String)

Schema validation failure.

CryptoError(CryptoError)

Failure within the cryptographic submodule.

ParseLimit(String)

Schema or validation hit some parsing limit.

Trait Implementations

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)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl Error for Error

fn custom<T: Display>(msg: T) -> Self

Used when a Serialize implementation encounters any error while serializing a type.

impl Error for Error

fn custom<T: Display>(msg: T) -> Self

Raised when there is general error when deserializing a type.

pub fn invalid_type(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a type different from what it was expecting.

pub fn invalid_value(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

pub fn invalid_length(len: usize, exp: &dyn Expected) -> Self

Raised when deserializing a sequence or map and the input data contains too many or too few elements.

pub fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize enum type received a variant with an unrecognized name.

pub fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize struct type received a field with an unrecognized name.

pub fn missing_field(field: &'static str) -> Self

Raised when a Deserialize struct type expected to receive a required field with a particular name but that field was not present in the input.

pub fn duplicate_field(field: &'static str) -> Self

Raised when a Deserialize struct type received more than one of the same field.

impl From<CryptoError> for Error

fn from(e: CryptoError) -> Self

Performs the conversion.
