#[non_exhaustive]
pub enum CraneliftOptLevel {
None,
Speed,
SpeedAndSize,
}
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.
