Trait TryExtend 

pub trait TryExtend<T> {
    type Error;

    // Required method
    fn try_extend<I: IntoIterator<Item = T>>(
        &mut self,
        iter: I,
    ) -> Result<(), Self::Error>;

    // Provided method
    fn try_extend_one(&mut self, item: T) -> Result<(), Self::Error> { ... }
}

Fallible variant of the Extend trait

Required Associated Types

type Error

The type returned in the event of an error.

Required Methods

fn try_extend<I: IntoIterator<Item = T>>( &mut self, iter: I, ) -> Result<(), Self::Error>

Tries to extends a collection with the contents of an iterator.

Provided Methods

fn try_extend_one(&mut self, item: T) -> Result<(), Self::Error>

Tries to extend a collection with exactly one element.

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
