Struct HeapValue 

pub struct HeapValue<'facet, const BORROW: bool = true> { /* private fields */ }

A type-erased value stored on the heap

The BORROW const generic indicates whether this value may contain borrowed data:

• BORROW = true (default): The value may contain references with lifetime 'facet
• BORROW = false: The value is fully owned and contains no borrowed data

Implementations

impl<'facet, const BORROW: bool> HeapValue<'facet, BORROW>

pub fn peek(&self) -> Peek<'_, 'facet>

Returns a peek that allows exploring the heap value.

pub fn shape(&self) -> &'static Shape

Returns the shape of this heap value.

pub fn materialize<T: Facet<'facet>>(self) -> Result<T, ReflectError>

Turn this heapvalue into a concrete type

impl<'facet, const BORROW: bool> HeapValue<'facet, BORROW>

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

Formats the value using its Display implementation, if available

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

Formats the value using its Debug implementation, if available

impl<'facet, const BORROW: bool> HeapValue<'facet, BORROW>

pub unsafe fn as_ref<T>(&self) -> &T

Unsafely get a reference to the underlying value as type T.

Safety

Caller must guarantee that the underlying value is of type T.

Trait Implementations

impl<'facet, const BORROW: bool> Debug for HeapValue<'facet, BORROW>

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

Formats the value using the given formatter.

impl<'facet, const BORROW: bool> Display for HeapValue<'facet, BORROW>

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

Formats the value using the given formatter.

impl<'facet, const BORROW: bool> Drop for HeapValue<'facet, BORROW>

fn drop(&mut self)

Executes the destructor for this type.

impl<'facet, const BORROW: bool> PartialEq for HeapValue<'facet, BORROW>

fn eq(&self, other: &Self) -> 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<'facet, const BORROW: bool> PartialOrd for HeapValue<'facet, BORROW>

fn partial_cmp(&self, other: &Self) -> 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.
