Enum std::convert::Infallible

pub enum Infallible {}

🔬 This is a nightly-only experimental API. (try_from #33417)

A type used as the error type for implementations of fallible conversion traits in cases where conversions cannot actually fail.

Because Infallible has no variants, a value of this type can never exist. It is used only to satisfy trait signatures that expect an error type, and signals to both the compiler and the user that the error case is impossible.

Trait Implementations

impl Debug for Infallible

fn fmt(&self, __arg_0: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for Infallible

fn hash<__H>(&self, __arg_0: &mut __H) where
    __H: Hasher, 

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 Clone for Infallible

fn clone(&self) -> Infallible

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialOrd<Infallible> for Infallible

fn partial_cmp(&self, __arg_0: &Infallible) -> 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 Ord for Infallible

fn cmp(&self, __arg_0: &Infallible) -> 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.

impl Display for Infallible

fn fmt(&self, &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for Infallible

impl PartialEq<Infallible> for Infallible

fn eq(&self, __arg_0: &Infallible) -> 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 From<Infallible> for TryFromIntError

fn from(infallible: Infallible) -> TryFromIntError

Performs the conversion.

impl Copy for Infallible

impl Error for Infallible

fn description(&self) -> &str

A short description of the error.

fn cause(&self) -> Option<&Error>

The lower-level cause of this error, if any.
