Struct ParamSet 

pub struct ParamSet {
    pub entries: Vec<(Symbol, Value)>,
}

An ordered set of name-to-Value parameter bindings for a model run.

The concrete inputs supplied to a FEMM evaluation; lookups are by Symbol and the whole set can be fingerprinted into a StableId. See the crate README for the FEM role of parameter sets.

Examples

use sim_lib_femm_core::ParamSet;
use sim_kernel::{DefaultFactory, Factory, Symbol};

let radius = Symbol::new("radius");
let value = DefaultFactory.string("0.5".to_owned()).unwrap();
let params = ParamSet::new(vec![(radius.clone(), value)]);
assert!(params.get(&radius).is_some());
assert!(params.symbols().contains(&radius));

Fields

entries: Vec<(Symbol, Value)>

The name/value bindings, in insertion order.

Implementations

impl ParamSet

pub fn new(entries: Vec<(Symbol, Value)>) -> Self

Build a ParamSet from name/value bindings.

pub fn get(&self, name: &Symbol) -> Option<&Value>

Look up the Value bound to name, if present.

pub fn symbols(&self) -> BTreeSet<Symbol>

Return the bound parameter names as a sorted set.

pub fn fingerprint(&self, cx: &mut Cx) -> StableId

Compute a content StableId over the displayed bindings.

Renders each value through the kernel’s display path under cx, so the fingerprint reflects value content rather than object identity.

Trait Implementations

impl Clone for ParamSet

fn clone(&self) -> ParamSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamSet

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

Formats the value using the given formatter.

impl Default for ParamSet

fn default() -> ParamSet

Returns the “default value” for a type.
