Function is_feature_enabled

Checks if a specific protocol feature flag is enabled.

Restricted to internal use within the sui-framework package only.
If we need to use it in sui-system, we can add friend declarations.
We should never need to expose this to user packages.

Arguments

• feature_flag_name - The name of the feature flag as bytes (e.g., b"enable_vdf")

• It is expected to be a valid UTF-8 string
• The flag should exist in the protocol config

Returns

• true if the feature is enabled in the current protocol version
• false if the feature is disabled

Example (for framework use only)

use sui::protocol_config;

if (protocol_config::is_feature_enabled(b"enable_accumulators")) \{
// Accumulators are available
\};

public(package) fun is_feature_enabled(feature_flag_name: vector<u8>): bool
