Struct BlockInitializeArgs

#[repr(C)]
pub struct BlockInitializeArgs {
    pub parent_hash_ptr: NonNull<<BlockHash as IoType>::PointerType>,
    pub parent_hash_size: NonNull<u32>,
}

Data structure containing expected input for external method invocation, eventually calling block_initialize() on the other side by the host.

This can be used with Env, though there are helper methods on this provided by extension trait that allow not dealing with this struct directly in simpler cases.

Fields

parent_hash_ptr: NonNull<<BlockHash as IoType>::PointerType>

parent_hash_size: NonNull<u32>

Size of the contents parent_hash_ptr points to
