Enum IndexDecodeError 

#[non_exhaustive]
pub enum IndexDecodeError {
    Decode(DecodeError),
    Index(IndexError),
    FormatMismatch {
        selected: Format,
        indexed: IndexKind,
    },
}

Failure while decoding through a caller-supplied index.

Index-driven decoding is strict: an invalid, incomplete, or source-mismatched index is reported rather than silently falling back to an unindexed path.

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.

Decode(DecodeError)

The compressed input could not be decoded and verified.

Index(IndexError)

The supplied index was invalid or did not describe the source.

FormatMismatch

The decoder’s selected container disagreed with the index provenance.

Fields

selected: Format

Container selected on the decoder builder.

indexed: IndexKind

Container provenance recorded by the index.

Trait Implementations

impl Clone for IndexDecodeError

fn clone(&self) -> IndexDecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexDecodeError

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

Formats the value using the given formatter.

impl Display for IndexDecodeError

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

Formats the value using the given formatter.

impl Error for IndexDecodeError

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<DecodeError> for IndexDecodeError

fn from(error: DecodeError) -> Self

Converts to this type from the input type.

impl From<IndexError> for IndexDecodeError

fn from(error: IndexError) -> Self

Converts to this type from the input type.
