Struct solana_program::message::v0::LoadedMessage

pub struct LoadedMessage<'a> {
    pub message: Cow<'a, Message>,
    pub loaded_addresses: Cow<'a, LoadedAddresses>,
    pub is_writable_account_cache: Vec<bool>,
}

Combination of a version #0 message and its loaded addresses

Fields

message: Cow<'a, Message>

Message which loaded a collection of lookup table addresses

loaded_addresses: Cow<'a, LoadedAddresses>

Addresses loaded with on-chain address lookup tables

is_writable_account_cache: Vec<bool>

List of boolean with same length as account_keys(), each boolean value indicates if corresponding account key is writable or not.
