Struct LuaStream 

pub struct LuaStream {
    pub f: Option<Box<dyn Read>>,
    pub closef: Option<fn(&mut LuaState) -> Result<usize, LuaError>>,
}

File-stream handle used by the IO library.

closef in C is a lua_CFunction. In Rust we store an optional closer.

Fields

f: Option<Box<dyn Read>>

The underlying file handle. None for incompletely opened or closed streams.

closef: Option<fn(&mut LuaState) -> Result<usize, LuaError>>

Optional close function (None for already-closed streams).
