features - [devnet]

此内容尚不支持你的语言。

Defines feature flags for Aptos. Those are used in Aptos specific implementations of features in the Move stdlib, the Aptos stdlib, and the Aptos framework.

============================================================================================ Feature Flag Definitions

Each feature flag should come with documentation which justifies the need of the flag. Introduction of a new feature flag requires approval of framework owners. Be frugal when introducing new feature flags, as too many can make it hard to understand the code.

Each feature flag should come with a specification of a lifetime:

a transient feature flag is only needed until a related code rollout has happened. This is typically associated with the introduction of new native Move functions, and is only used from Move code. The owner of this feature is obliged to remove it once this can be done.
a permanent feature flag is required to stay around forever. Typically, those flags guard behavior in native code, and the behavior with or without the feature need to be preserved for playback.

Note that removing a feature flag still requires the function which tests for the feature (like code_dependency_check_enabled below) to stay around for compatibility reasons, as it is a public function. However, once the feature flag is disabled, those functions can constantly return true.

use 0x1::error;
use 0x1::signer;
use 0x1::vector;

Resources

`Features`

The enabled features, represented by a bitset stored on chain.

struct Features has key

`PendingFeatures`

This resource holds the feature vec updates received in the current epoch. On epoch change, the updates take effect and this buffer is cleared.
