Enum CompressionError 

#[non_exhaustive]
pub enum CompressionError {
    FeatureDisabled(&'static str),
    InvalidData(String),
    TooLarge {
        limit: usize,
    },
    InvalidLevel {
        codec: &'static str,
        level: i32,
        reason: String,
    },
    Io(Error),
}

Errors that can occur during compression or decompression.

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.

FeatureDisabled(&'static str)

The requested codec was not enabled at compile time. The codec name is one of "gzip", "snappy", "lz4", "zstd".

InvalidData(String)

The codec could not parse the compressed payload. Examples are truncated input, bad framing, and an invalid checksum.

TooLarge

Decompression produced, or would produce, more output than the caller’s max_output cap allows. This guards against decompression bombs, that is a small compressed payload that expands to gigabytes.

Fields

limit: usize

InvalidLevel

The compression level is outside the range that Kafka accepts for the codec, or the codec has no levels. reason is the message of Kafka’s level validator (CompressionType.levelValidator).

Fields

codec: &'static str

The codec name: "none", "gzip", "snappy", "lz4" or "zstd".

level: i32

The level that the caller gave.

reason: String

Kafka’s message for the level.

Io(Error)

I/O error from one of the codec libraries.

Trait Implementations

impl Debug for CompressionError

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

Formats the value using the given formatter.

impl Display for CompressionError

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

Formats the value using the given formatter.

impl Error for CompressionError

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<Error> for CompressionError

fn from(source: Error) -> Self

Converts to this type from the input type.
