Trait TryExtend

Source 
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> { ... }
}
Expand description

Fallible variant of the Extend trait

Required Associated Types§

Source

type Error

The type returned in the event of an error.

Required Methods§

Source

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§

Source

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

Tries to extend a collection with exactly one element.

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.
