Struct VmContext

source 
pub struct VmContext<DB: ZephyrDatabase, L: LedgerStateRead> {
    pub vm: Option<Weak<Vm<DB, L>>>,
}
Expand description

VM Context. The object is currently simply a wrapper for an optional reference to the Virtual Machine.

Fields§

§vm: Option<Weak<Vm<DB, L>>>

Optional Zephyr Virtual Machine.
