Enum SequenceError 

#[non_exhaustive]
pub enum SequenceError {
    LengthMismatch,
    MatchTooShort {
        index: usize,
    },
    OffsetTooFar {
        index: usize,
    },
    ZeroOffset {
        index: usize,
    },
    BlockTooLarge,
    MatchMismatch {
        index: usize,
    },
}

Why a parse cannot build a valid frame.

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.

LengthMismatch

The parse covers more bytes than the input holds, or, with explicit block delimiters, not exactly the input.

MatchTooShort

Sequence index has an offset but matches fewer than MIN_MATCH bytes; a run of literals alone is a delimiter, with offset 0.

Fields

index: usize

Index of the sequence.

OffsetTooFar

Sequence index copies from further back than the output and the dictionary reach, or than the window allows.

Fields

index: usize

Index of the sequence.

ZeroOffset

Sequence index has a match but no offset.

Fields

index: usize

Index of the sequence.

BlockTooLarge

A block between two delimiters is larger than max_block.

MatchMismatch

Sequence index copies bytes that differ from the ones the input has where the copy lands, so the frame would decode to something else.

Fields

index: usize

Index of the sequence.
