Struct MinReg 

pub struct MinReg<T: Ord>(/* private fields */);

A register that merges by taking the minimum value.

Merge semantics: min(a, b).

Implementations

impl<T: Ord> MinReg<T>

pub fn new(value: T) -> Self

Create a new register with the given initial value.

pub fn value(&self) -> &T

Returns a reference to the current value.

pub fn set(&mut self, value: T)

Set a new value, unconditionally replacing the current one.

Trait Implementations

impl<T: Clone + Ord> Clone for MinReg<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Ord> Debug for MinReg<T>

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

Formats the value using the given formatter.

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

where T: Deserialize<'de> + Ord,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Ord + Clone + PartialEq> Lattice for MinReg<T>

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

Compute the least upper bound of self and other.

impl<T: PartialEq + Ord> PartialEq for MinReg<T>

fn eq(&self, other: &MinReg<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> Serialize for MinReg<T>

where T: Serialize + Ord,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
