Struct multiversx_sc::types::ManagedMap

#[repr(transparent)]
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

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 get_raw_handle(&self) -> RawHandle
