Enum CompressionError 

#[non_exhaustive]
pub enum CompressionError {
    FeatureDisabled(&'static str),
    InvalidData(String),
    TooLarge {
        limit: usize,
    },
    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 compressed payload could not be parsed (truncated input, bad framing, invalid checksum, etc.).

TooLarge

Decompression produced (or would produce) more output than the caller’s max_output cap allows. Guards against decompression bombs: a small compressed payload that expands to gigabytes.

Fields

limit: usize

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.
