Trait Joined 

pub(crate) trait Joined: IntoIterator {
    // Required method
    fn joined(self, sep: impl Display, f: &mut Formatter<'_>) -> Result;
}

Required Methods

fn joined(self, sep: impl Display, f: &mut Formatter<'_>) -> Result

Takes an iterator over elements that implement Display, and format them into f, separated by sep.

This is similar to Itertools::format, but instead of returning an implementation of Display, it formats directly into a Formatter.

The performance of joined is slightly better than format, since it doesn’t need to use a Cell to keep track of whether fmt was already called (joined’s API doesn’t allow it be called more than once).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
