Struct Inline 

#[repr(transparent)]
pub struct Inline<T>(pub T);

A ProtoBox that stores the message inline (no heap allocation).

MessageField<T, Inline<T>> is laid out as Option<T> — set values live directly in the parent struct. This eliminates the per-field allocation of the default Box<T> pointer at the cost of inflating the parent’s size by size_of::<T>() even when the field is unset.

Codegen uses this by default via PointerRepr::Inline, which is recursion-aware: a field that would form an infinite-size cycle is silently kept on Box. Opt out per-field with box_type_in(PointerRepr::Box, …).

Trait Implementations

impl<T: Clone> Clone for Inline<T>

fn clone(&self) -> Inline<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Inline<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for Inline<T>

fn default() -> Inline<T>

Returns the “default value” for a type.

impl<T> Deref for Inline<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T> DerefMut for Inline<T>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.

impl<T: Eq> Eq for Inline<T>

impl<T> From<T> for Inline<T>

Convenience mirror of Box’s From<T>; codegen and MessageField::some use ProtoBox::new instead.

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for Inline<T>

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<T: PartialEq> PartialEq for Inline<T>

fn eq(&self, other: &Inline<T>) -> bool

Equality operator ==.

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

Inequality operator !=.

impl<T> ProtoBox<T> for Inline<T>

fn new(value: T) -> Self

Box a freshly-decoded or constructed message value.

fn into_inner(self) -> T

Unwrap the pointer, returning the owned message value (the take / into_option path).
