Implementations§

source §

impl<const ENTRIES: usize> MetadataByteArrayRef<ENTRIES>

source

pub fn new( metadata_spec: &SideMetadataSpec, start: Address, bytes: usize ) -> Self

Get a piece of metadata address range as a byte array.

§Arguments

metadata_spec - The specification of the target side metadata.
start - The starting address of the heap range.
bytes - The size of the heap range.

source

pub const fn len(&self) -> usize

Get the length of the array.

source

pub fn get(&self, index: usize) -> u8

Get a byte from the metadata byte array at the given index.

source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

source §

impl<T> Borrow<T> for T
where T: ?Sized,

source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

§

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

§

impl<T> DowncastSync for T
where T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

source §

impl<T> From<T> for T

source §

fn from(t: T) -> T

Returns the argument unchanged.

source §

impl<T, U> Into for T
where U: From<T>,

source §

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

source §

impl<T> IntoEither for T

source §

fn into_either(self, into_left: bool) -> Either<Self, Self>

Converts self into a Left variant of Either<Self, Self> if into_left is true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more

source §

fn into_either_with<F>(self, into_left: F) -> Either<Self, Self>
where F: FnOnce(&Self) -> bool,

Converts self into a Left variant of Either<Self, Self> if into_left(&self) returns true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more
