Trait Join 

pub trait Join {
    // Required method
    fn write_join<I, W, T>(&self, writer: W, coll: T) -> Result<usize, Error>
       where I: Display,
             W: Write,
             T: IntoIterator<Item = I>;

    // Provided method
    fn join<I, T>(&self, coll: T) -> String
       where I: Display,
             T: IntoIterator<Item = I> { ... }
}

This trait brings the join and write_join methods into scope.

Required Methods

fn write_join<I, W, T>(&self, writer: W, coll: T) -> Result<usize, Error>

where I: Display, W: Write, T: IntoIterator<Item = I>,

Called on the separator, this takes a writer and something that can be turned into an iterator and writes the joined result to the writer.

Provided Methods

fn join<I, T>(&self, coll: T) -> String

where I: Display, T: IntoIterator<Item = I>,

Called on the separator, this takes something that can be turned into an iterator and produces a heap-allocated string

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.
