Struct PhantomMember

pub struct PhantomMember<T, const OLD: isize, const NEW: isize> { /* private fields */ }

A zero-sized marker used to access dynamically relocated members.

In the C++ class, it is not possible to simultaneously obtain mutable references to multiple fields due to Rust’s borrowing rules. To work around this, PhantomMember provides an API for safely accessing individual fields while respecting the newer runtime offsets.

This struct is a placeholder that allows access to relocated members by providing runtime-based offset calculations.

Generics

• T: Member type
• OLD: Offset when < ver.1_6_629
• NEW: Offset when >= ver.1_6_629

Implementations

impl<T, const OLD: isize, const NEW: isize> PhantomMember<T, OLD, NEW>

pub fn get(&self) -> Result<&T, RelocationError>

Retrieves a reference to the member as immutable.

Safety

This performs an unsafe relocation based on runtime version checks. Returns None if the relocation fails.

Errors

• This function may return an error if the module’s state cannot be accessed, or if the map_active call fails when fetching the current version.
• If the pointer is null
• If the pointer is unaligned

pub fn get_mut(&mut self) -> Result<&mut T, RelocationError>

Retrieves a mutable reference to the member.

Safety

This performs an unsafe relocation based on runtime version checks. Returns None if the relocation fails.

Errors

• This function may return an error if the module’s state cannot be accessed, or if the map_active call fails when fetching the current version.
• If the pointer is null
• If the pointer is unaligned

Trait Implementations

impl<T, const OLD: isize, const NEW: isize> Clone for PhantomMember<T, OLD, NEW>

Performs copy-assignment from source.

impl<T, const OLD: isize, const NEW: isize> Debug for PhantomMember<T, OLD, NEW>

where T: Debug,

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

Formats the value using the given formatter.

impl<T: Default, const OLD: isize, const NEW: isize> Default for PhantomMember<T, OLD, NEW>

fn default() -> PhantomMember<T, OLD, NEW>

Returns the “default value” for a type.

impl<T: Hash, const OLD: isize, const NEW: isize> Hash for PhantomMember<T, OLD, NEW>

impl<T: Ord, const OLD: isize, const NEW: isize> Ord for PhantomMember<T, OLD, NEW>

fn cmp(&self, other: &PhantomMember<T, OLD, NEW>) -> 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.

impl<T: PartialEq, const OLD: isize, const NEW: isize> PartialEq for PhantomMember<T, OLD, NEW>

fn eq(&self, other: &PhantomMember<T, OLD, NEW>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&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.
