Trait Join

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

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

This trait brings the join and write_join methods into scope.

Required Methods

fn write_join<I: AsRef<str>, W: Write, T: IntoIterator<Item = I>>( &self, writer: W, coll: T, ) -> Result<usize>

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: AsRef<str>, T: IntoIterator<Item = I>>(&self, coll: T) -> String

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.
