Trait Implementations

impl Cache<Memory> for Tree

fn frame(&self) -> &Vec<Rc<RefCell<State<Memory>>>>

Get frame

fn frame_mut(&mut self) -> &mut Vec<Rc<RefCell<State<Memory>>>>

Get frame mut

fn memory(&self) -> Option<Memory>

Memory

fn flush(&mut self) -> Option<()>

(lifecycle) Flush data

impl Frame<Memory> for Tree

fn active(&self) -> Option<[u8; 32]>

fn active_set(&self, key: [u8; 32], value: Vec<u8>) -> Option<Vec<u8>>

fn active_get(&self, key: &[u8]) -> Option<Vec<u8>>

fn push(&mut self, code_hash: [u8; 32], memory: Memory)

fn switch(&mut self, code_hash: [u8; 32]) -> Option<()>

fn back(&mut self) -> Option<()>

fn top(&mut self) -> Option<()>

impl From<Tree> for JsValue

fn from(value: Tree) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Tree

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for Tree

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for Tree

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<Tree>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for Tree

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for Tree

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for Tree

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<Tree>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for Tree

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<Tree>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl Storage for Tree

fn set(&mut self, key: Vec<u8>, value: Vec<u8>) -> Option<Vec<u8>>

set K for V

fn remove(&mut self, key: &[u8]) -> Option<Vec<u8>>

Remove a key

fn get(&self, key: &[u8]) -> Option<Vec<u8>>

get V by K

impl TryFromJsValue for Tree

type Error = JsValue

The type returned in the event of a conversion error.

fn try_from_js_value(value: JsValue) -> Result<Self, Self::Error>

Performs the conversion.

impl VectorFromWasmAbi for Tree

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[Tree]>

impl VectorIntoJsValue for Tree

fn vector_into_jsvalue(vector: Box<[Tree]>) -> JsValue

impl VectorIntoWasmAbi for Tree

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

fn vector_into_abi(vector: Box<[Tree]>) -> Self::Abi
