Struct Arguments

pub struct Arguments<'a, F: AsRef<str>, T: Display + ?Sized + 'a, I: IntoIterator<Item = &'a T> + Clone> { /* private fields */ }

This structure represents a format string combined with its arguments. In contrast with fmt::Arguments this structure can be easily and safely created at runtime.

Implementations

impl<'a, F: AsRef<str>, T: Display + ?Sized + 'a, I: IntoIterator<Item = &'a T> + Clone> Arguments<'a, F, T, I>

pub fn new(fmt: F, args: I) -> Self

Creates a new instance of a Displayable structure, representing formatted arguments. A runtime analog of format_args! macro. Extra arguments are ignored, missing arguments are replaced by empty string.

Examples:

dyn_fmt::Arguments::new("{}a{}b{}c", &[1, 2, 3]); // "1a2b3c"
dyn_fmt::Arguments::new("{}a{}b{}c", &[1, 2, 3, 4]); // "1a2b3c"
dyn_fmt::Arguments::new("{}a{}b{}c", &[1, 2]); // "1a2bc"
dyn_fmt::Arguments::new("{{}}{}", &[1, 2]); // "{}1"

Trait Implementations

impl<'a, F: Clone + AsRef<str>, T: Clone + Display + ?Sized + 'a, I: Clone + IntoIterator<Item = &'a T> + Clone> Clone for Arguments<'a, F, T, I>

fn clone(&self) -> Arguments<'a, F, T, I>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
