Trait EstimateSize 

pub trait EstimateSize {
    // Required method
    fn estimate_size(&self) -> usize;
}

Trait for estimating the memory size of cached values.

Implement this trait for custom types to enable accurate memory tracking.

Required Methods

fn estimate_size(&self) -> usize

Estimate the memory size of this value in bytes.

Dyn Compatibility

This trait is dyn compatible.

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