Struct grin_core::global::GLOBAL_CHAIN_TYPE

source · [−]

pub struct GLOBAL_CHAIN_TYPE { /* private fields */ }

Expand description

Global chain_type that must be initialized once on node startup. This is accessed via get_chain_type() which allows the global value to be overridden on a per-thread basis (for testing).

Methods from Deref<Target = OneTime<ChainTypes>>

source

pub fn init(&self, value: T)

Initializes the OneTime, should only be called once after construction. Will panic (via assert) if called more than once.

source

pub fn borrow(&self) -> T

Borrows the OneTime, should only be called after initialization. Will panic (via expect) if called before initialization.

source

pub fn is_init(&self) -> bool

Has this OneTime been initialized?
