Struct wasmer_types :: MetadataHeader Copy item path

impl MetadataHeader

pub const CURRENT_VERSION: u32 = 7u32

Current ABI version. Increment this any time breaking changes are made to the format of the serialized data.

pub const LEN: usize = 16usize

Length of the metadata header.

pub const ALIGN: usize = 16usize

Alignment of the metadata.

pub fn new(len: usize) -> Self

Creates a new header for metadata of the given length.

pub fn into_bytes(self) -> [u8; 16]

Convert the header into its bytes representation.

pub fn parse(bytes: &[u8]) -> Result<usize, DeserializeError>

Parses the header and returns the length of the metadata following it.
