Struct solana_runtime::feature::Feature

pub struct Feature {
    pub activated_at: Option<Slot>,
}

The Feature struct is the on-chain representation of a runtime feature.

Feature activation is accomplished by:

1. Activation is requested by the feature authority, who issues a transaction to create the feature account. The newly created feature account will have the value of Feature::default()
2. When the next epoch is entered the runtime will check for new activation requests and active them. When this occurs, the activation slot is recorded in the feature account

Fields

activated_at: Option<Slot>
