Enum finchers_core::Never

pub enum Never {}

A type which has no possible values.

Methods

impl Never

pub fn never_into<T>(self) -> T

Consume itself and transform into an arbitrary type.

NOTE: This function has never been actually called because the possible values don't exist.

Trait Implementations

impl Debug for Never

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

Formats the value using the given formatter.

impl Copy for Never

impl Clone for Never

fn clone(&self) -> Never

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for Never

fn eq(&self, __arg_0: &Never) -> 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 for Never

fn partial_cmp(&self, __arg_0: &Never) -> 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 Never

fn cmp(&self, __arg_0: &Never) -> 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 Eq for Never

impl Display for Never

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

Formats the value using the given formatter.

impl Error for Never

fn description(&self) -> &str

A short description of the error.

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

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

impl HttpError for Never

fn status_code(&self) -> StatusCode

Return the HTTP status code associated with this error type.

fn append_headers(&self, _: &mut HeaderMap<HeaderValue>)

Append a set of header values to the header map.

fn as_fail(&self) -> Option<&Fail>

Return the reference to a value of Fail if exists.
