Specific categories of decode errors.

Variants

UnexpectedEof

Unexpected end of input.

InvalidMagic

Invalid magic number (expected \0asm).

UnsupportedVersion

Unsupported WASM version.

Fields

found: u32

Leb128TooLong

LEB128 encoding exceeds the maximum number of bytes for the target type.

Leb128Overflow

UnknownSectionId

Unknown section ID.

Fields

id: u8

SectionOverflow

Section extends beyond the end of the binary.

SectionOutOfOrder

Sections are out of order (non-custom sections must be ordered by ID).

Fields

prev: u8

current: u8

DuplicateSection

Fields

id: u8

UnknownValType

Unknown value type encoding byte.

Fields

byte: u8

Fields

byte: u8

UnknownExportDesc

Unknown export descriptor tag.

Fields

byte: u8

InvalidMutability

Invalid global mutability encoding.

Fields

byte: u8

InvalidUtf8

Invalid UTF-8 in a name string.

FunctionCodeLengthMismatch

Fields

opcode: u32

UnexpectedByte

Unexpected byte value.

Fields

expected: u8

found: u8
