Struct Cost 

#[non_exhaustive]
pub struct Cost {
    pub cpu_nanos: u64,
    pub memory_bytes: u64,
    pub network_bytes: u64,
}

Estimated cost of executing a plan.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

cpu_nanos: u64

Estimated CPU time in nanoseconds.

memory_bytes: u64

Estimated peak memory in bytes.

network_bytes: u64

Estimated bytes transferred over the network.
