Struct uucore::shortcut_value_parser::ShortcutValueParser

pub struct ShortcutValueParser(_);

Implementations

impl ShortcutValueParser

ShortcutValueParser is similar to clap’s PossibleValuesParser: it verifies that the value is from an enumerated set of PossibleValue.

Whereas PossibleValuesParser only accepts exact matches, ShortcutValueParser also accepts shortcuts as long as they are unambiguous.

pub fn new(values: impl Into<Self>) -> Self

Trait Implementations

impl Clone for ShortcutValueParser

fn clone(&self) -> ShortcutValueParser

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<I, T> From<I> for ShortcutValueParserwhere I: IntoIterator<Item = T>, T: Into<PossibleValue>,

fn from(values: I) -> Self

Converts to this type from the input type.

impl TypedValueParser for ShortcutValueParser

type Value = String

Argument’s value type

fn parse_ref( &self, cmd: &Command, arg: Option<&Arg>, value: &OsStr ) -> Result<Self::Value, Error>

Parse the argument value

fn possible_values( &self ) -> Option<Box<dyn Iterator<Item = PossibleValue> + '_>>

Reflect on enumerated value properties

fn parse( &self, cmd: &Command, arg: Option<&Arg>, value: OsString ) -> Result<Self::Value, Error<RichFormatter>>

Parse the argument value

fn map<T, F>(self, func: F) -> MapValueParser<Self, F>where T: Send + Sync + Clone, F: Fn(Self::Value) -> T + Clone,

Adapt a TypedValueParser from one value to another

fn try_map<T, E, F>(self, func: F) -> TryMapValueParser<Self, F>where F: Fn(Self::Value) -> Result<T, E> + Clone + Send + Sync + 'static, T: Send + Sync + Clone, E: Into<Box<dyn Error + Sync + Send + 'static, Global>>,
