Struct lucet_module::owned::OwnedSparseData

pub struct OwnedSparseData { /* fields omitted */ }

A sparse representation of a Lucet module's initial heap.

This is a version of SparseData with owned Vec<u8>s representing pages. This type is useful when directly building up a value to be serialized.

Methods

impl OwnedSparseData

pub fn new(pages: Vec<Option<Vec<u8>>>) -> Result<Self, Error>

Create a new OwnedSparseData from its consitutent pages.

Entries in the pages argument which are Some must contain a vector of exactly the host page size (4096), otherwise this function returns Error::IncorrectPageSize. Entries which are None are interpreted as empty pages, which will be zeroed by the runtime.

pub fn to_ref<'a>(&'a self) -> SparseData<'a>

Create a SparseData backed by the values in this OwnedSparseData.
