VTable for generic containers with runtime trait resolution.

Uses OxPtrConst/OxPtrMut as receivers to access inner type’s shape at runtime. Used for Vec<T>, Option<T>, Arc<T>, etc.

Returns Option to indicate whether the operation is supported (the inner type may not implement the required trait).

Per-type operations

Note that drop_in_place, default_in_place, and clone_into are NOT in this struct. These operations must be monomorphized per-type and live in TypeOps on the crate::Shape. This allows vtables to be shared across generic instantiations (e.g., one vtable for all Vec<T>).

Safety

All function pointers are unsafe fn because they operate on raw pointers. Callers must ensure:

• The pointer points to a valid instance of the expected type
• The pointer has the correct alignment for the type
• For mutable operations, the caller has exclusive access to the data
• The lifetime of the data extends for the duration of the operation

Fields

display: Option<unsafe fn(OxPtrConst, &mut Formatter<'_>) -> Option<Result>>

Display function - formats value using Display trait.

debug: Option<unsafe fn(OxPtrConst, &mut Formatter<'_>) -> Option<Result>>

Debug function - formats value using Debug trait.

hash: Option<unsafe fn(OxPtrConst, &mut HashProxy<'_>) -> Option<()>>

Hash function - hashes value using Hash trait via HashProxy.

invariants: Option<unsafe fn(OxPtrConst) -> Option<Result<(), String>>>

Invariants function - checks type invariants.

parse: Option<unsafe fn(&str, OxPtrUninit) -> Option<Result<(), ParseError>>>

Parse function - parses value from string into uninitialized destination.

The destination is uninitialized memory. Implementations must use target.put(value) to write the parsed value, NOT *target.as_mut() = value which would try to drop uninitialized memory.

parse_bytes: Option<unsafe fn(&[u8], OxPtrUninit) -> Option<Result<(), ParseError>>>

Parse bytes function - parses value from byte slice into uninitialized destination. Used for binary formats where types have a more efficient representation.

The destination is uninitialized memory. Implementations must use target.put(value) to write the parsed value.

try_from: Option<unsafe fn(OxPtrUninit, &'static Shape, PtrConst) -> TryFromOutcome>

Try from function - converts from another value type into uninitialized destination.

Arguments

• dst: Uninitialized destination pointer where the converted value will be written
• src_shape: Shape of the source type
• src_ptr: Pointer to the source value

Return Value

Returns crate::TryFromOutcome which encodes both the result and ownership semantics:

• crate::TryFromOutcome::Converted: Success. Source was consumed.
• crate::TryFromOutcome::Unsupported: Source type not supported. Source was NOT consumed.
• crate::TryFromOutcome::Failed: Conversion failed. Source WAS consumed.

See VTableDirect::try_from for implementation patterns.

Safety

• dst must be valid for writes and properly aligned for the destination type
• src_ptr must point to valid, initialized memory of the type described by src_shape

Implementation Note

The destination is uninitialized memory. Implementations must use dst.put(value) to write the converted value, NOT *dst.as_mut() = value.

try_into_inner: Option<unsafe fn(OxPtrMut) -> Option<Result<PtrMut, String>>>

Try into inner function - extracts inner value (consuming).

try_borrow_inner: Option<unsafe fn(OxPtrConst) -> Option<Result<PtrMut, String>>>

Try borrow inner function - borrows inner value.

partial_eq: Option<unsafe fn(OxPtrConst, OxPtrConst) -> Option<bool>>

PartialEq function - tests equality with another value.

partial_cmp: Option<unsafe fn(OxPtrConst, OxPtrConst) -> Option<Option<Ordering>>>

PartialOrd function - compares with another value.

cmp: Option<unsafe fn(OxPtrConst, OxPtrConst) -> Option<Ordering>>

Ord function - total ordering comparison.
