Trait TryClone 

pub trait TryClone: Sized {
    // Required method
    fn try_clone(&self) -> Result<Self, AllocError>;

    // Provided method
    fn try_clone_from(&mut self, source: &Self) -> Result<(), AllocError> { ... }
}

Tries to clone, return an error instead of panic if allocation failed.

Required Methods

fn try_clone(&self) -> Result<Self, AllocError>

Provided Methods

fn try_clone_from(&mut self, source: &Self) -> Result<(), AllocError>

Performs copy-assignment from source.

a.try_clone_from(&b) is equivalent to a = b.try_clone() in functionality, but can be overridden to reuse the resources of a to avoid unnecessary allocations.

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.
