Enum MaybeOwnedValue 

pub enum MaybeOwnedValue<'a> {
    Borrowed(BorrowedValue<'a>),
    Owned(OwnedValue),
}

A value that may be either borrowed or owned.

This enum provides flexibility when the ownership semantics depend on runtime conditions.

Performance

The borrowed variant has zero allocation overhead. The owned variant allocates once on creation.

Variants

Borrowed(BorrowedValue<'a>)

A borrowed reference.

Owned(OwnedValue)

An owned value.

Implementations

impl<'a> MaybeOwnedValue<'a>

pub fn as_bytes(&self) -> &[u8]

Returns the value as a byte slice.

pub fn len(&self) -> usize

Returns the length of the value.

pub fn is_empty(&self) -> bool

Returns true if the value is empty.

pub fn into_owned(self) -> OwnedValue

Converts to an owned value, cloning if necessary.

pub fn is_borrowed(&self) -> bool

Returns true if this is a borrowed value.

pub fn is_owned(&self) -> bool

Returns true if this is an owned value.

Trait Implementations

impl<'a> AsRef<[u8]> for MaybeOwnedValue<'a>

fn as_ref(&self) -> &[u8]

impl<'a> Clone for MaybeOwnedValue<'a>

fn clone(&self) -> MaybeOwnedValue<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for MaybeOwnedValue<'a>

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

Formats the value using the given formatter.

impl<'a> From<BorrowedValue<'a>> for MaybeOwnedValue<'a>

fn from(value: BorrowedValue<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<OwnedValue> for MaybeOwnedValue<'a>

fn from(value: OwnedValue) -> Self

Converts to this type from the input type.
