Struct Cmd

pub struct Cmd<R, W>
where
    W: Write + 'static,
    R: BufRead + 'static,
{ /* private fields */ }

Command interpreter implemented as struct that contains boxed CommandHandlers in a hashmap with Strings as the keys

Implementations

impl<R, W> Cmd<R, W>

where W: Write + 'static, R: BufRead + 'static,

pub fn new(reader: R, writer: W) -> Cmd<R, W>

where W: Write, R: Read,

Create new Cmd instance

pub fn run(&mut self) -> Result<(), Error>

Start the command interpreter

Handlers with return code 0 will break the loop

pub fn add_cmd_fn( &mut self, name: String, handler: impl Fn(&mut W, &[&str]) -> CommandResult + 'static, ) -> Result<(), Error>

Insert new handler into the Cmd handles HashMap defined by a function or closure

Note: Will not overwrite existing handler names

pub fn add_cmd( &mut self, name: String, handler: impl CommandHandler<W> + 'static, ) -> Result<(), Error>

Insert new handler into the Cmd handles HashMap

Note: Will not overwrite existing handler names
