Struct SymbolTable 

pub struct SymbolTable<Id, T> { /* private fields */ }

A symbol table mapping IDs to values.

Used for roles, sections, parameters, materials, and outputs. Provides O(1) lookup by ID and iteration in insertion order.

Implementations

impl<Id: Eq + Hash + Clone, T> SymbolTable<Id, T>

pub fn new() -> Self

Create a new empty symbol table.

pub fn insert(&mut self, id: Id, value: T) -> Result<(), Id>

Insert an item, returning an error if the ID already exists.

pub fn insert_or_replace(&mut self, id: Id, value: T)

Insert an item, overwriting if it already exists.

pub fn get(&self, id: &Id) -> Option<&T>

Get an item by ID.

pub fn get_mut(&mut self, id: &Id) -> Option<&mut T>

Get a mutable reference to an item by ID.

pub fn contains(&self, id: &Id) -> bool

Check if an ID exists in the table.

pub fn iter(&self) -> impl Iterator<Item = (&Id, &T)>

Iterate over all (ID, value) pairs in insertion order.

pub fn values(&self) -> impl Iterator<Item = &T>

Iterate over all values in insertion order.

pub fn keys(&self) -> impl Iterator<Item = &Id>

Iterate over all IDs in insertion order.

pub fn len(&self) -> usize

Get the number of items.

pub fn is_empty(&self) -> bool

Check if the table is empty.
