Trait Input

pub trait Input {
    // Required methods
    fn parsed(&self) -> bool;
    fn has_default(&self) -> bool;
    fn parse(&mut self, token: &str) -> CliResult<bool>;
    fn display_name(&self) -> String;
    fn description(&self) -> Option<String>;
    fn type_name(&self) -> InputType;
    fn is_bool_flag(&self) -> bool;
    fn complete(&mut self, value: &str) -> CliResult<Vec<String>>;

parser complexities:

compound flags (-am)

optional flags

out of order flags

Required Methods

fn parsed(&self) -> bool

fn has_default(&self) -> bool

fn parse(&mut self, token: &str) -> CliResult<bool>

fn display_name(&self) -> String

fn description(&self) -> Option<String>

fn type_name(&self) -> InputType

fn is_bool_flag(&self) -> bool

fn complete(&mut self, value: &str) -> CliResult<Vec<String>>

must not return completions that don’t start with value, otherwise bash breaks
