Trait StatsReader

pub trait StatsReader: Send + Sync {
    // Required method
    fn count_entries<T>(&self) -> Result<usize, ProviderError>
       where T: Table;
}

Available on crate feature provider only.

The trait for fetching provider statistics.

Required Methods

fn count_entries<T>(&self) -> Result<usize, ProviderError>

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.
