Struct trivial_argument_parser::argument::parsable_argument::ParsableValueArgument

pub struct ParsableValueArgument<V> { /* private fields */ }

Structure which defines how given argument should be handled. Allows for automatic parsing and validation. Mutable borrow to parsable argument definition has to be registered in ArgumentList. Because of that registered arguments cannot be used while those borrows exist. Either ArgumentList instance has to be dropped or there are no further usages of it. This method of defining arguments is preferred as oposed to using the legacy API.

Implementations

impl<V> ParsableValueArgument<V>

pub fn new<C>( identification: ArgumentIdentification, handler: C ) -> ParsableValueArgument<V>where C: Fn(&mut Peekable<&mut Iter<'_, String>>, &mut Vec<V>) -> Result<(), String> + 'static,

pub fn first_value(&self) -> Option<&V>

pub fn values(&self) -> &Vec<V>

impl ParsableValueArgument<i64>

pub fn new_integer( identification: ArgumentIdentification ) -> ParsableValueArgument<i64>

Default integer type argument value handler. Checks whether value contains only digits or starts with minus sign.

impl ParsableValueArgument<String>

pub fn new_string( identification: ArgumentIdentification ) -> ParsableValueArgument<String>

Default string type argument value handler.

Trait Implementations

impl<'a, V> HandleableArgument<'a> for ParsableValueArgument<V>

fn handle( &mut self, input_iter: &mut Peekable<&mut Iter<'_, String>> ) -> Result<(), String>

Handles argument. Gets all needed values from input iterator.

fn is_by_short(&self, name: char) -> bool

Check if this argument is identified by specified short name.

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

Check if this argument is identified by specified long name.

fn identification(&self) -> &ArgumentIdentification

Get this arguments identification.
