Implementations

source

impl Table

source

pub fn new(ctx: impl AsContextMut, table_type: TableType) -> Self

Creates a new table to the store.

source

pub fn table_type(&self, ctx: impl AsContext) -> TableType

Returns the type and limits of the table.

Panics

Panics if ctx does not own this Table.

source

pub fn len(&self, ctx: impl AsContext) -> usize

Returns the current length of the table.

Note

The returned length must be valid within the resizable limits of the table entity.

Panics

Panics if ctx does not own this Table.

source

pub fn grow(
 &self,
 ctx: impl AsContextMut,
 grow_by: usize
) -> Result<(), TableError>

Grows the table by the given amount of elements.

Note

The newly added elements are initialized to None.

Errors

If the table is grown beyond its maximum limits.

Panics

Panics if ctx does not own this Table.

source

pub fn get(
 &self,
 ctx: impl AsContext,
 offset: usize
) -> Result<Option<Func>, TableError>

Returns the element at the given offset if any.

Errors

If the accesses element is out of bounds of the table.

Panics

Panics if ctx does not own this Table.

source

pub fn set(
 &self,
 ctx: impl AsContextMut,
 offset: usize,
 new_value: Option<Func>
) -> Result<(), TableError>

Sets a new value to the table element at the given offset.

Errors

If the accesses element is out of bounds of the table.

Panics

Panics if ctx does not own this Table.

T: ?Sized,

const: unstable · source

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

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

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

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. Read more

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

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

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. Read more

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. Read more

const: unstable · source

fn from(t: T) -> T

Returns the argument unchanged.

source

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

const: unstable · 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> ToOwned for T where
T: Clone,

type Owned = T

The resulting type after obtaining ownership.

source

fn to_owned(&self) -> T

U: TryFrom<T>,

type Error = >::Error

The type returned in the event of a conversion error.

const: unstable · source

fn try_into(self) -> Result<U, >::Error>
