Struct State 

pub struct State(/* private fields */);

Type-safe heterogeneous state container.

Stores values keyed by their TypeId, allowing type-safe insertion and retrieval. Used for dependency injection and cross-procedure shared state.

Follows rspc’s State pattern with NoOpHasher optimization.

Implementations

impl State

pub fn new() -> Self

pub fn insert<T: Send + Sync + 'static>(&mut self, value: T)

Insert a value. Replaces any existing value of the same type.

pub fn get<T: Send + Sync + 'static>(&self) -> Option<&T>

Get a reference to a stored value by type.

pub fn get_mut<T: Send + Sync + 'static>(&mut self) -> Option<&mut T>

Get a mutable reference to a stored value by type.

pub fn contains<T: Send + Sync + 'static>(&self) -> bool

Check if a value of the given type exists.

pub fn remove<T: Send + Sync + 'static>(&mut self) -> Option<T>

Remove and return a stored value by type.

Trait Implementations

impl Debug for State

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

Formats the value using the given formatter.

impl Default for State

fn default() -> Self

Returns the “default value” for a type.
