Everything that can go wrong parsing, encoding, or deserializing ABX data.

Variants

InvalidMagic

The 4-byte ABX\0 magic header didn’t match at the start of the input.

Fields

expected: [u8; 4]

The magic bytes this crate expects (ABX\0).

actual: [u8; 4]

The bytes actually found at the start of the input.

UnexpectedEof(&'static str)

The input ended before a complete token or value could be read.

BadInternedIndex(u16)

An interned-string back-reference pointed past the end of the pool.

InvalidUtf8

A string’s bytes were not valid UTF-8.

UnknownAttributeType(u8)

An attribute value’s type nibble didn’t match any known TYPE_* constant.

UnknownCommand(u8)

A token’s command nibble didn’t match any known CMD_* constant.

ValueTooLong

A string or byte blob was too long to fit the wire format’s u16 length prefix.

Fields

len: usize

The value’s actual length in bytes.

max: usize

The maximum length the wire format can express (u16::MAX, 65,535).

Nom(String)

The underlying nom parser failed; the message is nom’s own formatted error.

Io(Error)

A read or write on the underlying Read/Write failed.

Deserialization(String)

Mapping decoded ABX events onto a serde type failed (serialize feature).

Xml(String)

Parsing XML text failed while encoding it to ABX (xml feature).

Trait Implementations

impl Debug for AbxError

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

Formats the value using the given formatter.

impl Display for AbxError

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

Formats the value using the given formatter.

impl Error for AbxError

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 Error for AbxError

fn custom<T: Display>(msg: T) -> Self

Raised when there is general error when deserializing a type.

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

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

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.

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.

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

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

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

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

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.

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

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

impl<I: Debug> From<Err<Error<I>>> for AbxError

fn from(e: Err<Error<I>>) -> Self

Converts to this type from the input type.

impl From<Error> for AbxError

fn from(source: Error) -> Self

Converts to this type from the input type.
