Struct DiscordAssignment 

pub struct DiscordAssignment { /* private fields */ }

Discord assignment D_A : C -> P(K).

In v0.83 this is a materialized map from context id to discord set. Production builds will compute this lazily from a registry of detectors against an Atlas; that wiring lands when the Atlas presheaf does (target v0.8).

Implementations

impl DiscordAssignment

pub fn empty() -> Self

Empty assignment: no discord at any context.

pub fn build_from_detectors<D: Detector>( detectors: &[D], contexts: &[ContextId], ) -> Self

Build from a registry of detectors evaluated over a finite set of contexts.

Each detector is invoked once per context. If fires returns true, the corresponding kind is added to that context’s discord set.

pub fn set(&mut self, context: impl Into<ContextId>, kinds: DiscordSet)

Set the discord set at a single context.

pub fn get(&self, context: &str) -> DiscordSet

Get the discord set at a context, or empty if absent.

pub fn iter(&self) -> impl Iterator<Item = (&ContextId, &DiscordSet)>

Iterate (context, discord_set) pairs.

pub fn frontier_support(&self) -> FrontierSupport

Frontier support: the set of contexts where any discord kind fires.

pub fn context_count(&self) -> usize

Number of contexts in this assignment.

Trait Implementations

impl Clone for DiscordAssignment

fn clone(&self) -> DiscordAssignment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiscordAssignment

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

Formats the value using the given formatter.

impl Default for DiscordAssignment

fn default() -> DiscordAssignment

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DiscordAssignment

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DiscordAssignment

fn eq(&self, other: &DiscordAssignment) -> 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 DiscordAssignment

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
