Trait Implementations

impl AttrValue for NonZeroUsize

fn display(&self) -> String

Display the value, typically using std::fmt::Display. This is called to show the output in human-readable form.

fn parse(s: &str) -> Result<Self, Error>

Parse a value from a string, typically using std::str::FromStr.

impl Clone for NonZeroUsize

fn clone(&self) -> NonZeroUsize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NonZeroUsize

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NonZeroUsize

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NonZeroUsize

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

Formats the value using the given formatter.

impl From<NonZero<usize>> for NonZeroUsize

fn from(value: NonZeroUsize) -> Self

Converts to this type from the input type.

impl From<NonZeroUsize> for NonZeroUsize

fn from(value: NonZeroUsize) -> Self

Converts to this type from the input type.

impl From<NonZeroUsize> for usize

fn from(value: NonZeroUsize) -> Self

Converts to this type from the input type.

impl Named for NonZeroUsize

fn typename() -> &'static str

The globally unique type name for the type. This should typically be the fully qualified Rust name of the type.

fn typehash() -> u64

A globally unique hash for this type. TODO: actually enforce perfect hashing

fn typeid() -> TypeId

The TypeId for this type. TypeIds are unique only within a binary, and should not be used for global identification.

fn port() -> u64

A globally unique numeric identifier for this type.

fn arm(&self) -> Option<&'static str>

If the named type is an enum, this returns the name of the arm of the value self.

unsafe fn arm_unchecked(self_: *const ()) -> Option<&'static str>

An unsafe version of ‘arm’, accepting a pointer to the value, for use in type-erased settings.

impl PartialEq for NonZeroUsize

fn eq(&self, other: &NonZeroUsize) -> 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 Serialize for NonZeroUsize

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<usize> for NonZeroUsize

type Error = NonZeroUsizeError

The type returned in the event of a conversion error.

fn try_from(value: usize) -> Result<Self, Self::Error>

Performs the conversion.
