Struct BoundedCell 

pub struct BoundedCell<T: Storable, M: Memory = DefaultMemoryImpl> { /* private fields */ }

A stable cell whose writes enforce the record’s declared Storable bound.

Implementations

impl<T: Storable, M: Memory> BoundedCell<T, M>

pub fn init(memory: RuntimeMemory<M>, value: T) -> Self

Open a current cell or initialize a fresh bounded record.

Panics

Panics for unbounded records or encodings that violate the declared bound.

pub fn get(&self) -> &T

Read the cached current record without serializing or cloning it.

pub fn set(&mut self, value: T) -> T

Validate and persist a complete replacement, returning the prior record.

Panics

Panics before writing if the encoding violates its declared bound.
