Struct sp_core::traits::RuntimeCode

pub struct RuntimeCode<'a> {
    pub code_fetcher: &'a dyn FetchRuntimeCode,
    pub heap_pages: Option<u64>,
    pub hash: Vec<u8>,
}

The Wasm code of a Substrate runtime.

Fields

code_fetcher: &'a dyn FetchRuntimeCode

The code fetcher that can be used to lazily fetch the code.

heap_pages: Option<u64>

The optional heap pages this code should be executed with.

If None are given, the default value of the executor will be used.

hash: Vec<u8>

The SCALE encoded hash of code.

The hashing algorithm isn’t that important, as long as all runtime code instances use the same.

Implementations

impl<'a> RuntimeCode<'a>

pub fn empty() -> Self

Create an empty instance.

This is only useful for tests that don’t want to execute any code.

Trait Implementations

impl<'a> Clone for RuntimeCode<'a>

fn clone(&self) -> RuntimeCode<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> FetchRuntimeCode for RuntimeCode<'a>

fn fetch_runtime_code(&self) -> Option<Cow<'_, [u8]>>

Fetch the runtime :code.

impl<'a> PartialEq<RuntimeCode<'a>> for RuntimeCode<'a>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
