Enum BindPolicy 

#[non_exhaustive]
pub enum BindPolicy {
    Adaptive,
    Eager,
    Lazy,
}

How SchemaProgram::bind chooses a regular-schema bind mode; Naive stays low-level-only.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Adaptive

Packed table when affordable, else lazy trie-backed rows. The default.

Eager

Always the packed table: fastest per-mask query, higher bind cost.

Lazy

Always lazy trie-backed rows: cheap bind, each row cached on first query.
