Required Methods

fn account_matches_owners( &self, account: &Pubkey, owners: &[Pubkey], ) -> Option<usize>

fn get_account_shared_data(&self, pubkey: &Pubkey) -> Option<AccountSharedData>

Provided Methods

fn add_builtin_account(&self, _name: &str, _program_id: &Pubkey)

fn inspect_account( &self, _address: &Pubkey, _account_state: AccountState<'_>, _is_writable: bool, )

fn get_current_epoch_vote_account_stake(&self, _vote_address: &Pubkey) -> u64

fn calculate_fee( &self, _message: &impl SVMMessage, _lamports_per_signature: u64, _prioritization_fee: u64, _feature_set: &FeatureSet, ) -> FeeDetails

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.
