Trait IsSingleton 

pub trait IsSingleton {
    // Required method
    fn is_singleton(&self) -> bool;
}

A trait for checking whether a table/fragment is a singleton.

Required Methods

fn is_singleton(&self) -> bool

Returns true if the table/fragment is a singleton.

By singleton, we mean that all data read from or written to the storage belongs to the only SINGLETON_VNODE. This must be consistent with the behavior of TableDistribution. As a result, the vnode_count of such table/fragment can be 1.

Dyn Compatibility

This trait is dyn compatible.

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