Struct EntityMap

pub struct EntityMap<T> { /* private fields */ }

A structure to keep information for Entity as a key.

Implementations

impl<T> EntityMap<T>

pub fn new(global: T) -> EntityMap<T>

Creates an empty EntityMap.

pub fn is_empty(&self) -> bool

Verifies whether anything was set beside a global entry.

pub fn get(&self, pos: Position) -> &T

Get a value for an Entity.

pub fn remove(&mut self, entity: Entity)

Removes a value for an Entity.

impl<T> EntityMap<T>

where T: Clone,

pub fn insert(&mut self, entity: Entity, value: T)

Set a value for an Entity.

Trait Implementations

impl<T> AsRef<T> for EntityMap<T>

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<T> Clone for EntityMap<T>

where T: Clone,

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<C> Colors for EntityMap<Option<C>>

where C: ANSIFmt + PartialEq,

type Color = C

Color implementation.

fn get_color( &self, pos: Position, ) -> Option<&<EntityMap<Option<C>> as Colors>::Color>

Returns a color for a given position.

fn is_empty(&self) -> bool

Verifies whether a map is empty or not.

impl<T> Debug for EntityMap<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for EntityMap<T>

where T: Default,

fn default() -> EntityMap<T>

Returns the “default value” for a type.

impl<T> PartialEq for EntityMap<T>

where T: PartialEq,

fn eq(&self, other: &EntityMap<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> Eq for EntityMap<T>

where T: Eq,

impl<T> StructuralPartialEq for EntityMap<T>
