Struct AllocSlice

#[repr(C)]
pub struct AllocSlice<T, Alloc> {
    pub start: AllocPtr<T, Alloc>,
    pub end: NonNull<T>,
}

A helper to work with allocated slices.

Fields

start: AllocPtr<T, Alloc>

The start of the slice.

end: NonNull<T>

The end of the slice (exclusive).

Implementations

impl<T, Alloc> AllocSlice<T, Alloc>

where Struct<FieldPair<AllocPtr<T, Alloc>, NonNull<T>>>: IStable, NonNull<T>: IStable, AllocPtr<T, Alloc>: IStable,

pub const fn has_optimal_layout() -> bool

Returns true if the layout for AllocSlice is smaller or equal to that Rust would have generated for it.

impl<T, Alloc> AllocSlice<T, Alloc>

pub const fn len(&self) -> usize

Returns the number of elements in the slice.

pub const fn is_empty(&self) -> bool

Returns true if the slice is empty.

pub const unsafe fn as_slice(&self) -> &[T]

Returns this slice.

Safety

self must be valid.

Trait Implementations

impl<T, Alloc> Clone for AllocSlice<T, Alloc>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug, Alloc: Debug> Debug for AllocSlice<T, Alloc>

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

Formats the value using the given formatter.

impl<T, Alloc> IStable for AllocSlice<T, Alloc>

where Struct<FieldPair<AllocPtr<T, Alloc>, NonNull<T>>>: IStable, NonNull<T>: IStable, AllocPtr<T, Alloc>: IStable,

const REPORT: &'static TypeReport

A compile-time generated report of the fields of the type, allowing for compatibility inspection.

const ID: u64

A stable (and ideally unique) identifier for the type. Often generated using crate::report::gen_id, but can be manually set.

type ForbiddenValues = <Struct<FieldPair<AllocPtr<T, Alloc>, NonNull<T>>> as IStable>::ForbiddenValues

The values that the annotated type cannot occupy.

type UnusedBits = <Struct<FieldPair<AllocPtr<T, Alloc>, NonNull<T>>> as IStable>::UnusedBits

The padding bits in the annotated types

type Size = <Struct<FieldPair<AllocPtr<T, Alloc>, NonNull<T>>> as IStable>::Size

The size of the annotated type in bytes.

type Align = <Struct<FieldPair<AllocPtr<T, Alloc>, NonNull<T>>> as IStable>::Align

The alignment of the annotated type in bytes.

type HasExactlyOneNiche = <Struct<FieldPair<AllocPtr<T, Alloc>, NonNull<T>>> as IStable>::HasExactlyOneNiche

Allows the detection of whether or not core::option::Options are stable:

type ContainsIndirections = <Struct<FieldPair<AllocPtr<T, Alloc>, NonNull<T>>> as IStable>::ContainsIndirections

Whether or not the type contains indirections (pointers, indices in independent data-structures…)

fn size() -> usize

Returns the size of the type.

fn align() -> usize

Returns the alignment of the type.

unsafe fn is_invalid(ptr: *const u8) -> bool

Returns true if ptr points to memory that cannot be a valid value of Self.

impl<T: Ord, Alloc: Ord> Ord for AllocSlice<T, Alloc>

fn cmp(&self, other: &AllocSlice<T, Alloc>) -> 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<T: PartialEq, Alloc: PartialEq> PartialEq for AllocSlice<T, Alloc>

fn eq(&self, other: &AllocSlice<T, Alloc>) -> 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<T: PartialOrd, Alloc: PartialOrd> PartialOrd for AllocSlice<T, Alloc>

fn partial_cmp(&self, other: &AllocSlice<T, Alloc>) -> 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.
