Struct DiscordSet 

pub struct DiscordSet { /* private fields */ }

A subset of DiscordKind. An element of the lattice L = P(K).

Empty means agreement / no detected discord at this context.

Implementations

impl DiscordSet

pub fn empty() -> Self

Empty set: no discord detected.

pub fn singleton(kind: DiscordKind) -> Self

Single-kind discord set.

pub fn from_kinds(kinds: impl IntoIterator<Item = DiscordKind>) -> Self

Build from any iterable of kinds.

pub fn is_empty(&self) -> bool

Whether this set is empty (no discord detected).

pub fn len(&self) -> usize

Number of kinds in this set.

pub fn contains(&self, kind: DiscordKind) -> bool

Whether kind is in this set.

pub fn insert(&mut self, kind: DiscordKind) -> bool

Insert a kind. Returns true if newly inserted.

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

Pointwise union (the lattice join).

pub fn meet(&self, other: &Self) -> Self

Pointwise intersection (the lattice meet).

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

Whether self is a subset of other.

pub fn iter(&self) -> impl Iterator<Item = DiscordKind> + '_

Iterate kinds in canonical (sorted) order.

Trait Implementations

impl Clone for DiscordSet

fn clone(&self) -> DiscordSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiscordSet

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

Formats the value using the given formatter.

impl Default for DiscordSet

fn default() -> DiscordSet

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DiscordSet

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DiscordSet

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

Formats the value using the given formatter.

impl Ord for DiscordSet

fn cmp(&self, other: &DiscordSet) -> 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 PartialEq for DiscordSet

fn eq(&self, other: &DiscordSet) -> 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 PartialOrd for DiscordSet

fn partial_cmp(&self, other: &DiscordSet) -> 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 Serialize for DiscordSet

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
