pub trait OrdLowerBound {
// Required method
fn cmp_lower_bound(&self, other: &Self) -> Ordering;
}Expand description
Trait for ordering keys by their lower bound (e.g. start for range-based keys).
This ordering is used exclusively by the merger’s min-heap to stream keys out in
left-to-right order (by start). It is distinct from OrdUpperBound and is not used
with search keys.
Required Methods§
fn cmp_lower_bound(&self, other: &Self) -> Ordering
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
