    pub heap_pages: Option<u64>,
    pub hash: Vec<u8>,
}

[−] Expand description

The Wasm code of a Substrate runtime.

Fields

code_fetcher: &'a dyn FetchRuntimeCode

[−] Expand description

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

heap_pages: Option<u64>

[−] Expand description

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>

[−] Expand description

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>[+]

[+] Show hidden undocumented items

fn clone(&self) -> RuntimeCode<'a>[−]

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

impl<'a> FetchRuntimeCode for RuntimeCode<'a>[+]

[+] Show hidden undocumented items

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

Fetch the runtime :code.

impl<'a> PartialEq<RuntimeCode<'a>> for RuntimeCode<'a>[+]

[+] Show hidden undocumented items

fn eq(&self, other: &Self) -> bool[−]

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

[+] Expand attributes

#[must_use]pub fn ne(&self, other: &Rhs) -> bool[−]

This method tests for !=.
