Struct dharitri_wasm::types::ManagedRef

pub struct ManagedRef<'a, M, T>
where
    M: ManagedTypeApi,
    T: ManagedType<M>,
{ /* private fields */ }

A very efficient reference to a managed type, with copy semantics.

It copies the handle and knows how to deref back.

Implementations

impl<'a, M, T> ManagedRef<'a, M, T>

where M: ManagedTypeApi, T: ManagedType<M>,

pub fn new(value: &'a T) -> Self

Trait Implementations

impl<'a, M, T> Borrow<T> for ManagedRef<'a, M, T>

where M: ManagedTypeApi, T: ManagedType<M>,

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<'a, M, T> Clone for ManagedRef<'a, M, T>

where M: ManagedTypeApi, T: ManagedType<M>,

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, M, T> Debug for ManagedRef<'a, M, T>

where M: ManagedTypeApi, T: ManagedType<M> + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, M, T> Deref for ManagedRef<'a, M, T>

where M: ManagedTypeApi, T: ManagedType<M>,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a, M, T> From<&'a T> for ManagedRef<'a, M, T>

where M: ManagedTypeApi, T: ManagedType<M>,

fn from(value_ref: &'a T) -> Self

Converts to this type from the input type.

impl<'a, M, T> NestedEncode for ManagedRef<'a, M, T>

where M: ManagedTypeApi, T: ManagedType<M> + NestedEncode,

fn dep_encode<O: NestedEncodeOutput>( &self, dest: &mut O ) -> Result<(), EncodeError>

NestedEncode to output, using the format of an object nested inside another structure. Does not provide compact version.

fn dep_encode_or_exit<O, ExitCtx>( &self, dest: &mut O, c: ExitCtx, exit: fn(_: ExitCtx, _: EncodeError) -> ! )

where O: NestedEncodeOutput, ExitCtx: Clone,

Version of top_decode that exits quickly in case of error. Its purpose is to create smaller implementations in cases where the application is supposed to exit directly on decode error.

impl<'a, M, T> PartialEq for ManagedRef<'a, M, T>

where M: ManagedTypeApi, T: ManagedType<M> + PartialEq,

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, M, T> TopEncode for ManagedRef<'a, M, T>

where M: ManagedTypeApi, T: ManagedType<M> + TopEncode,

fn top_encode<O: TopEncodeOutput>(&self, output: O) -> Result<(), EncodeError>

Attempt to serialize the value to ouput.

fn top_encode_or_exit<O, ExitCtx>( &self, output: O, c: ExitCtx, exit: fn(_: ExitCtx, _: EncodeError) -> ! )

where O: TopEncodeOutput, ExitCtx: Clone,

Version of top_decode that exits quickly in case of error. Its purpose is to create smaller bytecode implementations in cases where the application is supposed to exit directly on decode error.

impl<'a, M, T> Copy for ManagedRef<'a, M, T>

where M: ManagedTypeApi, T: ManagedType<M>,

impl<'a, M, T> Eq for ManagedRef<'a, M, T>

where M: ManagedTypeApi, T: ManagedType<M> + PartialEq,
