Struct TypedVTableDirectBuilder 

pub struct TypedVTableDirectBuilder<T> { /* private fields */ }

Type-safe builder for VTableDirect.

Generic over T at the type level, ensuring all function pointers are for the same type. The transmute to erased pointers happens inside the builder methods.

Implementations

impl<T> TypedVTableDirectBuilder<T>

pub const fn display(self, f: fn(&T, &mut Formatter<'_>) -> Result) -> Self

Set the display function.

pub const fn debug(self, f: fn(&T, &mut Formatter<'_>) -> Result) -> Self

Set the debug function.

pub const fn hash(self, f: fn(&T, &mut HashProxy<'static>)) -> Self

Set the hash function.

Pass <T as Hash>::hash::<HashProxy> to use the type’s Hash impl.

pub const fn invariants(self, f: fn(&T) -> Result<(), String>) -> Self

Set the invariants function.

pub const fn parse( self, f: unsafe fn(&str, *mut T) -> Result<(), ParseError>, ) -> Self

Set the parse function.

pub const fn parse_bytes( self, f: unsafe fn(&[u8], *mut T) -> Result<(), ParseError>, ) -> Self

Set the parse_bytes function.

For types with efficient binary representations (e.g., UUID as 16 bytes).

pub const fn try_from( self, f: unsafe fn(*mut T, &'static Shape, PtrConst) -> Result<(), String>, ) -> Self

Set the try_from function. Arguments: (dst, src_shape, src_ptr)

pub const fn try_into_inner( self, f: unsafe fn(*mut T) -> Result<PtrMut, String>, ) -> Self

Set the try_into_inner function.

For transparent types, this extracts the inner value (consuming). Takes a pointer to the wrapper type, returns a pointer to the inner value.

pub const fn try_borrow_inner( self, f: unsafe fn(*const T) -> Result<PtrMut, String>, ) -> Self

Set the try_borrow_inner function.

For transparent types, this borrows the inner value. Takes a pointer to the wrapper type, returns a pointer to the inner value.

pub const fn partial_eq(self, f: fn(&T, &T) -> bool) -> Self

Set the partial_eq function.

pub const fn partial_cmp(self, f: fn(&T, &T) -> Option<Ordering>) -> Self

Set the partial_cmp function.

pub const fn cmp(self, f: fn(&T, &T) -> Ordering) -> Self

Set the cmp function.

pub const fn build(self) -> VTableDirect

Build the VTable.
