Struct Args

pub struct Args { /* private fields */ }

Represents the arguments passed to the application.

See ARGS more detailed information.

Implementations

impl Args

pub fn len(&self) -> usize

Returns the number of command-line arguments passed to the application.

Examples

use ftkit::ARGS;

println!("count: {}", ARGS.len());

pub fn is_empty(&self) -> bool

Returns whether the process was executed without any arguments.

Note that this is very unlikely. Even when no concrete arguments are passed to the process, its name is still used as the first and only argument.

use ftkit::ARGS;

assert!(!ARGS.is_empty());

Trait Implementations

impl Debug for Args

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Index<usize> for Args

type Output = str

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'a> IntoIterator for &'a Args

type Item = &'a str

The type of the elements being iterated over.

type IntoIter = ArgsIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
