Struct StableVec 

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

Governed upstream Vec; initialization and failures follow upstream contracts.

Implementations

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

pub fn create(memory: RuntimeMemory<M>) -> Self

Create a collection only in zero-page memory.

Panics

Refuses nonempty memory before writing. Growth and codec failures retain upstream behavior.

pub fn reset(memory: RuntimeMemory<M>) -> Self

Deliberately replace any contents in this admitted allocation.

Panics

Growth and codec failures retain upstream behavior.

pub fn load(memory: RuntimeMemory<M>) -> Self

Load retained collection state without initializing a replacement.

Panics

Refuses empty or foreign memory and incompatible layouts/bounds without writing. Record decoding and backing failures retain upstream behavior.

pub fn get(&self, index: u64) -> Option<T>

Delegates to upstream Vec::get with the governed allocation.

pub fn set(&self, index: u64, item: &T)

Delegates to upstream Vec::set with the governed allocation.

pub fn push(&self, item: &T)

Delegates to upstream Vec::push with the governed allocation.

pub fn pop(&self) -> Option<T>

Delegates to upstream Vec::pop with the governed allocation.

pub fn len(&self) -> u64

Delegates to upstream Vec::len with the governed allocation.

pub fn is_empty(&self) -> bool

Delegates to upstream Vec::is_empty with the governed allocation.

pub fn iter(&self) -> impl DoubleEndedIterator<Item = T> + '_

Delegates to upstream Vec::iter with the governed allocation.
