Struct Cost

#[non_exhaustive]
pub struct Cost {
    pub actual_cost: u32,
    pub requested_query_cost: u32,
    pub execution_time: Option<DateTime<Utc>>,
}

Cost and cost statistics.

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.

actual_cost: u32

requested_query_cost: u32

execution_time: Option<DateTime<Utc>>

pub fn with_actual_cost(self, val: u32) -> Self
