Struct aws_smithy_cbor::decode::DeserializeError

pub struct DeserializeError { /* private fields */ }

When any of the decode methods are called they look for that particular data type at the current position. If the CBOR data tag does not match the type, a DeserializeError is returned.

Implementations

impl DeserializeError

pub fn unexpected_union_variant(unexpected_type: Type, at: usize) -> Self

More than one union variant was detected: unexpected_type was unexpected.

pub fn unknown_union_variant(variant_name: &str, at: usize) -> Self

Unknown union variant was detected. Servers reject unknown union varaints.

pub fn mixed_union_variants(at: usize) -> Self

More than one union variant was detected, but we never even got to parse the first one. We immediately raise this error when detecting a union serialized as a fixed-length CBOR map whose length (specified upfront) is a value different than 1.

pub fn expected_end_of_stream(at: usize) -> Self

Expected end of stream but more data is available.

pub fn custom(message: impl Into<Cow<'static, str>>, at: usize) -> Self

Returns a custom error with an offset.

pub fn is_type_mismatch(&self) -> bool

An unexpected type was encountered.

Trait Implementations

impl Debug for DeserializeError

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

Formats the value using the given formatter.

impl Display for DeserializeError

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

Formats the value using the given formatter.

impl Error for DeserializeError

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
