Struct MapSource 

pub struct MapSource { /* private fields */ }

A map-based source that looks up values by StatId.

Useful when you have a collection of stat values that you want to use as sources. Returns 0.0 for stats not in the map.

Examples

use zzstat::source::{MapSource, StatSource};
use zzstat::{StatId, StatContext};
use std::collections::HashMap;

let mut values = HashMap::new();
values.insert(StatId::from_str("HP"), 100.0);
values.insert(StatId::from_str("MP"), 50.0);

let source = MapSource::new(values);
let context = StatContext::new();

assert_eq!(source.get_value(&StatId::from_str("HP"), &context), 100.0);
assert_eq!(source.get_value(&StatId::from_str("MP"), &context), 50.0);
assert_eq!(source.get_value(&StatId::from_str("ATK"), &context), 0.0);

Implementations

impl MapSource

pub fn new(values: HashMap<StatId, f64>) -> Self

Create a new MapSource from a HashMap.

Examples

use zzstat::source::MapSource;
use zzstat::StatId;
use std::collections::HashMap;

let mut values = HashMap::new();
values.insert(StatId::from_str("HP"), 100.0);
let source = MapSource::new(values);

pub fn empty() -> Self

Create a new empty MapSource.

Examples

use zzstat::source::MapSource;

let mut source = MapSource::empty();
source.insert(zzstat::StatId::from_str("HP"), 100.0);

pub fn insert(&mut self, stat_id: StatId, value: f64)

Insert a value into the map.

Examples

use zzstat::source::MapSource;

let mut source = MapSource::empty();
source.insert(zzstat::StatId::from_str("HP"), 100.0);

Performs copy-assignment from source.

impl Debug for MapSource

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

Formats the value using the given formatter.

impl StatSource for MapSource

fn get_value(&self, stat_id: &StatId, _context: &StatContext) -> f64

Get the value for a stat from this source.
