}

Fields

header: Header

tail: Tail

Implementations

impl<Header, Tail: ?Sized> DynStruct<Header, Tail>

pub fn new(header: Header, tail: DynArg<Tail>) -> Box<Self>

Allocate a new DynStruct on the heap.

pub unsafe fn transmute<T: Pointee<Metadata = <Tail as Pointee>::Metadata> + ?Sized>( self: Box<Self>, ) -> Box<T>

SAFETY: DynStruct<Header, Tail> and T must have the same exact memory layout, including fields, size, and alignment. They must also have the same pointer metadata.

This function checks at compile-type the pointer metadata part. Use [more_unsafe_transmute] if that check fails for some reason.

pub unsafe fn more_unsafe_transmute<T: ?Sized>(self: Box<Self>) -> Box<T>

SAFETY: DynStruct<Header, Tail> and T must have the same exact memory layout, including fields, size, and alignment. They must also have the same pointer metadata.

This function does not check at compile-type the pointer metadata part. Make sure the metadatas are the same or you will get some confusing runtime bugs.

Trait Implementations

impl<Header: Clone, Tail: Clone + ?Sized> Clone for DynStruct<Header, Tail>

fn clone(&self) -> DynStruct<Header, Tail>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Header: Debug, Tail: Debug + ?Sized> Debug for DynStruct<Header, Tail>

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

Formats the value using the given formatter.

impl<Header: Hash, Tail: Hash + ?Sized> Hash for DynStruct<Header, Tail>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<Header: Ord, Tail: Ord + ?Sized> Ord for DynStruct<Header, Tail>

fn cmp(&self, other: &DynStruct<Header, Tail>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<Header: PartialEq, Tail: PartialEq + ?Sized> PartialEq for DynStruct<Header, Tail>

fn eq(&self, other: &DynStruct<Header, Tail>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl<Header: PartialOrd, Tail: PartialOrd + ?Sized> PartialOrd for DynStruct<Header, Tail>

fn partial_cmp(&self, other: &DynStruct<Header, Tail>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
