Enum ProtocolError 

#[non_exhaustive]
pub enum ProtocolError {
    UnexpectedEof {
        needed: usize,
    },
    InvalidValue(&'static str),
    InvalidUtf8(Utf8Error),

}

Errors that can occur during wire-protocol encoding or decoding.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnexpectedEof

Decode reached end of buffer before the expected number of bytes.

Fields

needed: usize

InvalidValue(&'static str)

Decoded a value that the schema says is impossible, such as a negative array length.

InvalidUtf8(Utf8Error)

Decoded UTF-8 bytes that are not valid UTF-8.

VarintTooLong

Decoded a varint that exceeds the maximum legal length.

Fields

max: usize

UnsupportedVersion

Encountered an unknown API version for a known API key.

Fields

api_key: i16

version: i16

SchemaMismatch(&'static str)

Schema version requested is not within the message’s supported range.

TagNotValidForVersion

Decoded a known KIP-482 tag at a version that its schema does not declare. The text matches the exception that Kafka’s generated read method throws.

Fields

tag: u32

version: i16

Trait Implementations

impl Debug for ProtocolError

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

Formats the value using the given formatter.

impl Display for ProtocolError

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

Formats the value using the given formatter.

impl Error for ProtocolError

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<RecordsError> for ProtocolError

fn from(e: RecordsError) -> Self

Converts to this type from the input type.
