Struct BlockInitializeArgs 

pub struct BlockInitializeArgs<'external_args> {
    pub parent_root_ptr: NonNull<<BlockRoot as IoType>::PointerType>,
    pub parent_root_size: u32,
    pub parent_root_capacity: u32,
    /* private fields */
}

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_root_ptr: NonNull<<BlockRoot as IoType>::PointerType>

parent_root_size: u32

Size of the contents parent_root_ptr points to

parent_root_capacity: u32

Capacity of the contents parent_root_ptr points to

Implementations
