Struct Owned 

pub struct Owned(/* private fields */);

An owned opaque value descriptor.

A value of this type encapsulates an opaque value descriptor. Cloning it duplicates the descriptor. Dropping it closes the descriptor. CBOR-encoding it yields an integer with the Identifier tag.

Implementations

impl Owned

pub const unsafe fn new(raw: u32) -> Self

Wraps a raw integer descriptor in a Descriptor object.

Safety

The caller must ensure that the passed-in value is a valid, open descriptor. Passing a closed descriptor may result in dropping the object closing an unrelated opaque value which happened to be allocated the same descriptor value. Passing an invalid descriptor value may violate the niche requirements and result in undefined behaviour.

The caller must ensure that only one Descriptor object for a given value exists at a time, because dropping a Descriptor object closes the descriptor.

pub const fn into_inner(self) -> u32

Destroys a Descriptor object and returns the raw value.

The caller must ensure that the descriptor is eventually closed. This function is safe because Rust’s safety guarantees to not include reliable freeing of resources; however, care should be taken when calling it.

pub const fn as_raw(&self) -> u32

Returns the raw descriptor value.

pub fn dup(&self) -> Result<Self>

Duplicates the descriptor.

Errors

• TooManyDescriptors is returned if the descriptor table is too full and some descriptors must be closed.

Trait Implementations

impl AsDescriptor for Owned

fn as_descriptor(&self) -> Borrowed<'_>

Borrows the descriptor.

impl AsRaw for Owned

fn as_raw(&self) -> u32

Returns the raw descriptor value.

impl Debug for Owned

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

Formats the value using the given formatter.

impl Drop for Owned

fn drop(&mut self)

Executes the destructor for this type.

impl<Context> Encode<Context> for Owned

fn encode<W: Write>( &self, e: &mut Encoder<W>, _: &mut Context, ) -> Result<(), Error<W::Error>>

Encode a value of this type using the given Encoder.

fn is_nil(&self) -> bool

Is this value of Self a nil value?

impl Hash for Owned

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 IntoDescriptor for Owned

fn into_descriptor(self) -> Owned

Converts to the descriptor.

impl Ord for Owned

fn cmp(&self, other: &Owned) -> 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 PartialEq for Owned

fn eq(&self, other: &Owned) -> 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 PartialOrd for Owned

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