Struct cosmwasm_vm::Checksum

source · [−]

pub struct Checksum(_);

Expand description

A SHA-256 checksum of a Wasm blob, used to identify a Wasm code. This must remain stable since this checksum is stored in the blockchain state.

This is often referred to as “code ID” in go-cosmwasm, even if code ID usually refers to an auto-incrementing number.

Implementations

source

impl Checksum

source

pub fn generate(wasm: &[u8 ]) -> Self

source

pub fn to_hex(self) -> String

Creates a lowercase hex encoded copy of this checksum.

This takes an owned self instead of a reference because Checksum is cheap to Copy.
