Expand description

Possible optimization levels for the Cranelift codegen backend.

Variants (Non-exhaustive)

This enum is marked as 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.

None

No optimizations performed, minimizes compilation time by disabling most optimizations.

Speed

Generates the fastest possible code, but may take longer.

SpeedAndSize

Similar to speed, but also performs transformations aimed at reducing code size.
