Enum rustc_transmute::Reason

pub enum Reason {
    SrcIsUnspecified,
    DstIsUnspecified,
    DstIsBitIncompatible,
    DstIsPrivate,
    DstIsTooBig,
}

Answers: Why wasn’t the source type transmutable into the destination type?

Variants

SrcIsUnspecified

The layout of the source type is unspecified.

DstIsUnspecified

The layout of the destination type is unspecified.

DstIsBitIncompatible

The layout of the destination type is bit-incompatible with the source type.

DstIsPrivate

There aren’t any public constructors for Dst.

DstIsTooBig

Dst is larger than Src, and the excess bytes were not exclusively uninitialized.

Trait Implementations

impl Clone for Reason

fn clone(&self) -> Reason

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Reason

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

Formats the value using the given formatter.

impl Hash for Reason

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 Ord for Reason

fn cmp(&self, other: &Reason) -> 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) -> Self where
    Self: PartialOrd<Self>, 

Restrict a value to a certain interval.

impl PartialEq<Reason> for Reason

fn eq(&self, other: &Reason) -> 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 !=.

impl PartialOrd<Reason> for Reason

fn partial_cmp(&self, other: &Reason) -> 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 Eq for Reason

impl StructuralEq for Reason

impl StructuralPartialEq for Reason

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
