Trait DatabaseCommit 

pub trait DatabaseCommit {
    // Required method
    fn commit(&mut self, changes: HashMap<Address, Account>);

    // Provided method
    fn commit_iter(
        &mut self,
        changes: impl IntoIterator<Item = (Address, Account)>,
    ) { ... }
}

EVM database commit interface.

Required Methods

fn commit(&mut self, changes: HashMap<Address, Account>)

Commit changes to the database.

Provided Methods

fn commit_iter(&mut self, changes: impl IntoIterator<Item = (Address, Account)>)

Commit changes to the database with an iterator.

Implementors of DatabaseCommit should override this method when possible for efficiency.

Callers should prefer using DatabaseCommit::commit when they already have a [HashMap].

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
