Enum CodecZstdDictError 

pub enum CodecZstdDictError {
    MissingHeader,
    MalformedHash(String),
    UnknownHash(String),
}

Raised when the server’s Codec-Zstd-Dict header doesn’t match any dict the client has loaded, or is missing on a zstd response.

A wrong-dict decompression would produce garbage bytes that downstream parsers would misinterpret — fail fast instead.

Variants

MissingHeader

Response was Content-Encoding: zstd but the server omitted the Codec-Zstd-Dict header. Per spec/PROTOCOL.md the server MUST name the dict it used; we refuse to guess.

MalformedHash(String)

Codec-Zstd-Dict value was not in the canonical sha256:<64 hex chars> shape. The wrapped string is the raw header value (trimmed) for diagnostics.

UnknownHash(String)

Codec-Zstd-Dict named a dict we haven’t loaded. The caller should fetch it from the tokenizer map’s zstd_dictionaries[] entry (the one whose hash matches) or retry the request with Accept-Encoding: gzip to downgrade to a no-dict path. The wrapped string is the declared hash.

Trait Implementations

impl Clone for CodecZstdDictError

fn clone(&self) -> CodecZstdDictError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CodecZstdDictError

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

Formats the value using the given formatter.

impl Display for CodecZstdDictError

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

Formats the value using the given formatter.

impl Error for CodecZstdDictError

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 PartialEq for CodecZstdDictError

fn eq(&self, other: &CodecZstdDictError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
