Struct Options 

pub struct Options {
    pub level: OptLevel,
    pub toggles: Vec<(String, bool)>,
    pub fuel: HashMap<String, u32>,
    pub dumps: Dumps,
    pub verify: bool,
}

What the command line asked the optimizer for.

Fields

level: OptLevel

Which pipeline to start from.

toggles: Vec<(String, bool)>

The passes -f<name> added and -fno-<name> removed, in the order they were given, so that the last mention of a pass is the one that decides.

fuel: HashMap<String, u32>

What -fpass-fuel=<pass>=<n> limited, by pass name.

dumps: Dumps

What -fdump-ir= asked to see.

verify: bool

Whether the verifier runs after every pass that changed anything.

Implementations

impl Options

pub fn for_level(level: OptLevel) -> Self

The options a level asks for on its own.

pub fn passes(&self) -> Vec<&'static dyn Pass>

The passes that will run, in order.

A pass named by -f<name> that the level did not choose is appended, because the only place it could go that does not need an ordering rule nobody wrote down is the end.

Trait Implementations

impl Clone for Options

fn clone(&self) -> Options

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Options

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Options

fn default() -> Self

The default level with nothing added to it, and the verifier on in a debug build, which is what section 9.10 asks for.

impl Eq for Options

impl PartialEq for Options

fn eq(&self, other: &Options) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
