Struct Max 

pub struct Max<T>(pub T);

Newtype wrapper for an Ord type where join is max.

• join = max(a, b)
• bottom = T::MIN (when T: Bounded)

Example

use algebra::JoinSemilattice;
use algebra::Max;

let a = Max(5);
let b = Max(10);
assert_eq!(a.join(&b), Max(10));

Tuple Fields

0: T

Trait Implementations

impl<T: Ord + Clone + Bounded> BoundedJoinSemilattice for Max<T>

fn bottom() -> Self

The bottom element of the lattice (⊥).

fn join_all_from_bottom<I>(it: I) -> Self

where I: IntoIterator<Item = Self>,

Join a finite iterator of values, starting from ⊥.

impl<T: Clone> Clone for Max<T>

fn clone(&self) -> Max<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Max<T>

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

Formats the value using the given formatter.

impl<T: Ord + Clone + Bounded> Default for Max<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for Max<T>

where T: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<T> for Max<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for Max<T>

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<T: Ord + Clone> JoinSemilattice for Max<T>

fn join(&self, other: &Self) -> Self

The join (least upper bound).

fn join_assign(&mut self, other: &Self)

In-place variant.

fn leq(&self, other: &Self) -> bool

where Self: PartialEq,

Derived partial order: x ≤ y iff x ⊔ y = y.

fn join_all<I>(it: I) -> Option<Self>

where I: IntoIterator<Item = Self>,

Join a finite iterator of values. Returns None for empty iterators.

impl<T: Named> Named for Max<T>

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

The globally unique port for this type. Typed ports are in the range of 1<<63..1<<64-1.

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<T: Ord> Ord for Max<T>

fn cmp(&self, other: &Max<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq for Max<T>

fn eq(&self, other: &Max<T>) -> 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<T: PartialOrd> PartialOrd for Max<T>

fn partial_cmp(&self, other: &Max<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T> Serialize for Max<T>

where T: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
