Implementations

impl DeserializationError

pub fn missing_data() -> DeserializationError

pub fn missing_struct_field( datatype: impl Into<DataType>, field_name: impl AsRef<str>, ) -> DeserializationError

pub fn mismatched_struct_field_lengths( field1_name: impl AsRef<str>, field1_length: usize, field2_name: impl AsRef<str>, field2_length: usize, ) -> DeserializationError

pub fn missing_union_arm( datatype: impl Into<DataType>, arm_name: impl AsRef<str>, arm_index: usize, ) -> DeserializationError

pub fn datatype_mismatch( expected: impl Into<DataType>, got: impl Into<DataType>, ) -> DeserializationError

pub fn offset_oob(offset: usize, len: usize) -> DeserializationError

pub fn offset_slice_oob(_: (usize, usize), len: usize) -> DeserializationError

pub fn downcast_error<ToType>() -> DeserializationError

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

Returns the unresolved backtrace associated with this error, if it exists.

Call resolve() on the returned _Backtrace to resolve it (costly!).

pub fn without_context(self) -> DeserializationError

The source of the error, without any Self::Context.

Trait Implementations

impl Debug for DeserializationError

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

Formats the value using the given formatter.

impl Display for DeserializationError

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

Formats the value using the given formatter.

impl Error for DeserializationError

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<DeserializationError> for ChunkError

fn from(source: DeserializationError) -> ChunkError

Converts to this type from the input type.
