Implementations

impl Flag

pub fn new<T: Into<String>>(
    name: T,
    flag_type: FlagType,
    description: T
) -> Flag

Creates a new instance of Flag

pub fn build_new(
    name: String,
    description: String,
    short_alias: Vector<char>,
    long_alias: Vector<String>,
    flag_type: FlagType,
    default_value: FlagValue
) -> Flag

Builds a new instance of Flags with all options.

pub fn with_name<T: Into<String>>(name: T) -> Self

Creates a new instance of Flag with name

pub fn with_name_and_type<T: Into<String>>(name: T, flag_type: FlagType) -> Self

Creates a new instance of Flag with name and type

pub fn new_bool<T: Into<String>>(name: T) -> Self

Creates a new instance of bool Flag

pub fn new_string<T: Into<String>>(name: T) -> Self

Creates a new instance of string Flag

pub fn new_int<T: Into<String>>(name: T) -> Self

Creates a new instance of int Flag

pub fn new_float<T: Into<String>>(name: T) -> Self

Creates a new instance of float Flag

pub fn short_alias<T: Into<char>>(self, a: T) -> Self

Add an short alias to this Flag

pub fn alias<T: Into<String>>(self, a: T) -> Self

Add an alias to this Flag

pub fn default_value(self, default_value: FlagValue) -> Self

Set this flag's default value

pub fn description<T: Into<String>>(self, description: T) -> Self

Set this flag's description

pub fn is(&self, name: &str) -> bool

Returns true if &self's name equals name of arg.

pub fn is_short(&self, alias: &char) -> bool

Returns true is alias equals one of short alias

pub fn any_short(&self, aliases: Chars<'_>) -> Vector<usize>

Returns positions alias in aliases matches one of short alias.

pub fn is_long(&self, alias: &str) -> bool

Returns true is alias equals one of long alias

pub fn get_name_clone(&self) -> String

Get this Flag's name's clone

pub fn derive_flag_value_from_string(&self, arg: String) -> FlagValue

Derives this Flag's value from arg Alias of self.flag_type.get_value_from_string(arg)

pub fn derive_flag_value_if_no_value(&self) -> FlagValue

Derives this Flag's value in case of no value Alias of self.flag_type.get_value_if_no_value()

pub fn help(&self, append_to: String, name_and_alias_min_width: usize) -> String

Add help for this flag to append_to. name_and_alias_min_width means min width of name and alias' field.
Flagに対するヘルプをappend_toに追加する。nameとalias表示部分のずれをある程度吸収できるようにその部分の最小幅をname_and_alias_min_widthで指定する
