Struct PlaygroundVarBytesArgs

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

Data structure containing expected input for external method invocation, eventually calling playground_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_ptr: NonNull<<VariableBytes<1024> as IoType>::PointerType>

_out_size: *mut u32

Size of the contents _out_ptr points to

_out_capacity: NonNull<u32>

Capacity of the allocated memory _out_ptr points to
