A message that does not match the schema, or is not valid msgpack.

Variants

Truncated

The input ended inside a value.

Fields

offset: usize

Byte offset in the primary frame where the value started.

needed: usize

Bytes missing past the end of the frame.

Type

A value of a different msgpack type than the schema allows.

Fields

expected: &'static str

What the schema allows here.

found: &'static str

The msgpack type found.

offset: usize

Byte offset in the primary frame.

IntRange

An integer outside the range of the schema’s type.

Fields

value: i128

The decoded integer.

target: &'static str

The schema type.

Utf8

A string that is not valid UTF-8.

Fields

offset: usize

Byte offset in the primary frame.

Tag

A tagged struct whose tag names a different message type.

Fields

expected: &'static str

The tag of the type being decoded.

found: String

The tag on the wire.

MissingField(&'static str)

A struct without a value for a field that has no default.

TrailingBytes(usize)

Bytes left in the primary frame after the top-level value.

Invalid(String)

A value the schema rejects for a reason other than its type.

Field

An error inside a named field, kept with the field name for context.

Fields

field: &'static str

The field being decoded.

source: Box<Error>

The underlying error.

Implementations

impl Error

pub fn in_field(self, field: &'static str) -> Self

Attach the name of the field being decoded.

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, __formatter: &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.
