source · [−]

#[non_exhaustive]
pub enum OptLevel {
    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.
