Struct ModuleHandle

pub struct ModuleHandle(/* private fields */);

A handle that obtains and holds the address of the surviving dll/exe until the end of program execution.

undefined behavior

If Self::new specifies a dll/exe that does not live until the end of program execution

Implementations

impl ModuleHandle

pub unsafe fn new<H>(module_name: H) -> Result<Self, ModuleHandleError>

where H: Param<PCWSTR>,

Gets the module handle of a module (exe, dll, etc.) that is being loaded by the calling process.

Example

use commonlibsse_ng::rel::module::ModuleHandle;
use windows::core::h; // `h!` is utf-16 str macro.

let handle = unsafe { ModuleHandle::new(h!("kernel32.dll")) };
assert!(handle.is_ok());

// If there is no extension, a `.dll` is automatically specified.(This is the behavior of `GetModuleHandleW` function.)
let handle = unsafe { ModuleHandle::new(h!("kernel32")) };
assert!(handle.is_ok());

Errors

• Errors if a module is specified that is not loaded by the calling process.
• If the specified module handle could not be obtained.

Safety

It is safe as long as specify a dll/exe that survives the 'static life time.

pub const fn try_as_nt_header( &self, ) -> Result<&IMAGE_NT_HEADERS64, ModuleHandleError>

Attempt to parse NT Header part.

Errors

When fail to parse as valid header.

Trait Implementations

impl Clone for ModuleHandle

fn clone(&self) -> ModuleHandle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ModuleHandle

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

Formats the value using the given formatter.

impl Default for ModuleHandle

fn default() -> Self

Returns the “default value” for a type.

impl Hash for ModuleHandle

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 Ord for ModuleHandle

fn cmp(&self, other: &ModuleHandle) -> 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.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ModuleHandle

fn eq(&self, other: &ModuleHandle) -> bool

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ModuleHandle

fn partial_cmp(&self, other: &ModuleHandle) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

fn le(&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.
