Struct ExampleVarBytesArgs

#[repr(C)]
pub struct ExampleVarBytesArgs {
    pub _out_ptr: NonNull<<VariableBytes<1024> as IoType>::PointerType>,
    pub _out_size: *mut u32,
    pub _out_capacity: NonNull<u32>,
    pub ok_result_ptr: NonNull<()>,
    pub ok_result_size: *mut u32,
    pub ok_result_capacity: NonNull<u32>,
}

Data structure containing expected input for external method invocation, eventually calling var_bytes() 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

_out_capacity: NonNull<u32>

Capacity of the allocated memory _out_ptr points to

ok_result_ptr: NonNull<()>

ok_result_size: *mut u32

Size of the contents ok_result_ptr points to

ok_result_capacity: NonNull<u32>
