Struct Unnormalized 

pub struct Unnormalized<I, T>
where
    I: Interner,
{
    value: T,
    _tcx: PhantomData<fn() -> I>,
}

A wrapper for values that need normalization.

FIXME(#155345): This is very WIP. The plan is to replace the skip_norm_wip spread throughout the codebase with proper normalization. This is the first step toward switching to eager normalization with the next solver. See the normalization refactor plan here.

We’re in a weird intermediate state as the change is too big to land in a single PR. While this work is in progress, just use Unnormalized::new_wip and Unnormalized::skip_norm_wip as needed.

The interner type parameter exists to constraint generic for certain impl, e.g., Unnormalized<I, I::Clause>.

Fields

value: T

_tcx: PhantomData<fn() -> I>

Implementations

impl<I, T> Unnormalized<I, T>

where I: Interner,

pub fn new(value: T) -> Unnormalized<I, T>

Should only be used in limited situations where you produce an potentially unnormalized value, like in (Early)Binder/GenericPredicates instantiation.

pub fn new_wip(value: T) -> Unnormalized<I, T>

FIXME: This is going to be eventually removed once we migrate the relevant APIs to return Unnormalized.

pub fn skip_normalization(self) -> T

Intentionally skip normalization. You probably should perform normalization in most cases.

pub fn skip_norm_wip(self) -> T

FIXME: This is going to be eventually removed. If you meet this in codebase, try using one of the normalization routines to consume the Unnormalized wrapper. Or use skip_normalization when normalization is really unnecessary.

Trait Implementations

impl<I, T> Clone for Unnormalized<I, T>

where I: Interner, T: Clone,

fn clone(&self) -> Unnormalized<I, T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<I, T> Debug for Unnormalized<I, T>

where I: Interner, T: Debug,

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

Formats the value using the given formatter.

impl<I, T> PartialEq for Unnormalized<I, T>

where I: Interner, T: PartialEq,

fn eq(&self, __other: &Unnormalized<I, T>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<I, T> PartialOrd for Unnormalized<I, T>

where I: Interner, T: PartialOrd,

fn partial_cmp(&self, __other: &Unnormalized<I, T>) -> 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.

impl<I, T> Copy for Unnormalized<I, T>

where I: Interner, T: Copy,

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
