Trait TryExtend 

pub trait TryExtend<T> {
    // Required method
    fn try_extend<I>(&mut self, iter: I) -> Result<(), OutOfMemory>
       where I: IntoIterator<Item = T>;
}

Analogue of Extend except handles OOM conditions.

Required Methods

fn try_extend<I>(&mut self, iter: I) -> Result<(), OutOfMemory>

where I: IntoIterator<Item = T>,

Extends self with the items from iter.

Returns an error if allocation fails while adding items to self. If an OOM happens then some items from iter may have been added to self already. On OOM no further items from the iterator will be consumed.

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.
