Struct ManagedMap

pub struct ManagedMap<M: ManagedTypeApi> { /* private fields */ }

A byte buffer managed by an external API.

Implementations

impl<M: ManagedTypeApi> ManagedMap<M>

pub fn new() -> Self

impl<M: ManagedTypeApi> ManagedMap<M>

pub fn get(&self, key: &ManagedBuffer<M>) -> ManagedBuffer<M>

pub fn put(&mut self, key: &ManagedBuffer<M>, value: &ManagedBuffer<M>)

pub fn remove(&mut self, key: &ManagedBuffer<M>) -> ManagedBuffer<M>

pub fn contains(&self, key: &ManagedBuffer<M>) -> bool

Trait Implementations

impl<M: ManagedTypeApi> Default for ManagedMap<M>

fn default() -> Self

Returns the “default value” for a type.

impl<M: ManagedTypeApi> ManagedType<M> for ManagedMap<M>

type OwnHandle = <M as HandleTypeInfo>::ManagedMapHandle

fn get_handle(&self) -> M::ManagedMapHandle

unsafe fn forget_into_handle(self) -> Self::OwnHandle

Forgets current object (does not run destructor), but extracts the handle.

fn transmute_from_handle_ref(handle_ref: &M::ManagedMapHandle) -> &Self

Implement carefully, since the underlying transmutation is an unsafe operation. For types that wrap a handle to some VM-managed data, make sure the type only contains the handle (plus ZSTs if necessary). For types that just wrap another managed type it is easier, call for the wrapped object.

fn transmute_from_handle_ref_mut( handle_ref: &mut M::ManagedMapHandle, ) -> &mut Self

fn get_raw_handle(&self) -> RawHandle

fn as_ref(&self) -> ManagedRef<'_, M, Self>
