Struct FnCommand 

pub struct FnCommand<F> { /* private fields */ }

Implementations

impl<F> FnCommand<F>

pub fn with_args(self, choices: &[&[&'static str]]) -> FnCommand<F>

One inner slice per position; trailing free-form args may be omitted.

pub fn with_value_choices( self, key: &'static str, values: &[&'static str], ) -> FnCommand<F>

First Tab completes to key=, subsequent Tabs cycle these values.

pub fn with_long_help(self, long: &'static str) -> FnCommand<F>

Trait Implementations

impl<Ctx, F> Command<Ctx> for FnCommand<F>

where F: FnMut(&[&str], &mut Ctx, &mut ConsoleWriter) -> Result<(), Error> + 'static,

fn name(&self) -> &str

fn help(&self) -> &str

fn long_help(&self) -> String

\n breaks paint as separate scrollback entries.

fn arg_choices(&self, arg_index: usize) -> &[&'static str]

fn arg_value_choices(&self, _arg_index: usize, key: &str) -> &[&'static str]

key carries no trailing =; empty means free-form.

fn run( &mut self, args: &[&str], ctx: &mut Ctx, out: &mut ConsoleWriter, ) -> Result<(), Error>

Recoverable issues go to out.error(..); unrecoverable ones return Err.

fn arg_choices_ctx<'a>( &'a self, arg_index: usize, prior: &[&str], ) -> &'a [&'static str]

prior is the arg tokens before the cursor.

fn arg_value_choices_ctx<'a>( &'a self, arg_index: usize, key: &str, prior: &[&str], ) -> &'a [&'static str]
