Enum rustc_transmute::Answer

pub enum Answer<R>where
    R: Ref,{
    Yes,
    No(Reason),
    IfTransmutable {
        src: R,
        dst: R,
    },
    IfAll(Vec<Answer<R>>),
    IfAny(Vec<Answer<R>>),
}

The type encodes answers to the question: “Are these types transmutable?”

Variants

Yes

Src is transmutable into Dst.

No(Reason)

Src is NOT transmutable into Dst.

IfTransmutable

Fields

src: R

dst: R

Src is transmutable into Dst, if src is transmutable into dst.

IfAll(Vec<Answer<R>>)

Src is transmutable into Dst, if all of the enclosed requirements are met.

IfAny(Vec<Answer<R>>)

Src is transmutable into Dst if any of the enclosed requirements are met.

Implementations

impl<R> Answer<R>where
    R: Ref,

pub(crate) fn and(self, rhs: Self) -> Self

pub(crate) fn or(self, rhs: Self) -> Self

Trait Implementations

impl<R: Clone> Clone for Answer<R>where
    R: Ref,

fn clone(&self) -> Answer<R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R: Debug> Debug for Answer<R>where
    R: Ref,

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

Formats the value using the given formatter.

impl<R: Hash> Hash for Answer<R>where
    R: Ref,

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,

Feeds a slice of this type into the given Hasher.

impl<R: Ord> Ord for Answer<R>where
    R: Ref,

fn cmp(&self, other: &Answer<R>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl<R: PartialEq> PartialEq<Answer<R>> for Answer<R>where
    R: Ref,

fn eq(&self, other: &Answer<R>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<R: PartialOrd> PartialOrd<Answer<R>> for Answer<R>where
    R: Ref,

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl<R: Eq> Eq for Answer<R>where
    R: Ref,

impl<R> StructuralEq for Answer<R>where
    R: Ref,

impl<R> StructuralPartialEq for Answer<R>where
    R: Ref,

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.
