Trait Lifetime 

pub trait Lifetime {
    // Required methods
    unsafe fn leak(&self) -> &'static Self;
    unsafe fn leak_mut(&self) -> &'static mut Self;
}

Trait for types that can be converted to a 'static reference.

This trait provides a way to obtain a 'static reference or mutable reference from a reference to Self, enabling safe lifetime extension for certain use cases where the object is known to live for the entire program duration.

Required Methods

unsafe fn leak(&self) -> &'static Self

Converts a reference to Self into a 'static reference.

Returns

• &'static Self: A reference to the instance with a 'static lifetime.

Safety

• The address is guaranteed to be a valid Self instance that was previously converted from a reference and is managed by the runtime.

unsafe fn leak_mut(&self) -> &'static mut Self

Converts a reference to Self into a 'static mutable reference.

Returns

• &'static mut Self: A mutable reference to the instance with a 'static lifetime.

Safety

• The address is guaranteed to be a valid Self instance that was previously converted from a reference and is managed by the runtime.

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.
