Module cranelift_codegen::settings
source · [−]Expand description
Shared settings module.
This module defines data structures to access the settings defined in the meta language.
Each settings group is translated to a Flags
struct either in this module or in its
ISA-specific settings
module. The struct provides individual getter methods for all of the
settings as well as computed predicate flags.
The Flags
struct is immutable once it has been created. A Builder
instance is used to
create it.
Example
use cranelift_codegen::settings::{self, Configurable};
let mut b = settings::builder();
b.set("opt_level", "speed_and_size");
let f = settings::Flags::new(b);
assert_eq!(f.opt_level(), settings::OptLevel::SpeedAndSize);
