Struct HostFunctions

Source

pub struct HostFunctions;

Expand description

Aggregate of all host functions exposed by this crate.

Plug this into your node’s HostFunctions tuple alongside the other host-function sets (e.g. [sp_io::SubstrateHostFunctions]). At runtime, register a VirtManagerExt wrapping your backend on the externalities before any of these host functions are invoked — without it, every call panics. All other interaction with the virtualization machinery should go through Module, Instance, and Execution. Provides implementations for the extern host functions.
