Struct arithmetic_eval::exec::WildcardId

pub struct WildcardId;

Module identifier that has a single possible value, which is displayed as *.

This type is a ModuleId-compatible replacement of (); () does not implement Display and thus cannot implement ModuleId directly.

Trait Implementations

impl Clone for WildcardId

fn clone(&self) -> WildcardId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WildcardId

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

Formats the value using the given formatter.

impl Default for WildcardId

fn default() -> WildcardId

Returns the “default value” for a type.

impl Display for WildcardId

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

Formats the value using the given formatter.

impl Hash for WildcardId

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<WildcardId> for WildcardId

fn eq(&self, other: &WildcardId) -> 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.
