Enum Goal 

pub enum Goal {
    Speed,
    Size,
}

Which of a target’s two tables is wanted.

A named type rather than a bare bool, because table(true) at a call site is a coin toss for the reader and table(Goal::Size) is not.

Variants

Speed

Make it fast. -O1, -O2, -O3.

Size

Make it small. -Os and -Oz.

Implementations

impl Goal

pub const fn for_size(size: bool) -> Self

The goal for a level that has already been asked whether it optimizes for size.

Takes the answer rather than the level, because the level lives in rucc-session and this crate sits below it. That is not a workaround for the layer rule, it is the layer rule working: what an instruction costs on a machine has nothing to do with how the driver was invoked, and a dependency the other way would say it did. The caller writes Goal::for_size(level.is_size()), which is one line and reads correctly.

pub const fn as_str(self) -> &'static str

The goal as it appears in a dump.

Trait Implementations

impl Clone for Goal

fn clone(&self) -> Goal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Goal

impl Debug for Goal

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

Formats the value using the given formatter.

impl Display for Goal

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

Formats the value using the given formatter.

impl Eq for Goal

impl Hash for Goal

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Goal

fn cmp(&self, other: &Goal) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Goal

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Goal

fn partial_cmp(&self, other: &Goal) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
