Everything that can go wrong finding a module or hooking a function.

Messages name the module, and the address relative to its base where one is involved.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ModuleNotLoaded

The module is not loaded in this process.

Fields

module: &'static str

The module’s file name.

BuildMismatch

The loaded module is none of the builds the bindings accept.

Fields

module: &'static str

The module’s file name.

found: Build

The build that is loaded.

expected: &'static [Build]

The builds the bindings accept.

InvalidImage

The loaded module’s headers could not be read.

Fields

module: &'static str

The module’s file name.

NotInitialized

The module has not been initialized; call its init first.

Fields

module: &'static str

The module’s file name.

VerificationFailed(Box<Mismatch>)

A function does not start with the bytes the bindings expect, and nothing else found it; see Mismatch.

NotInBuild

The loaded build’s IR lacks the function, and neither the byte pattern of a build that has it nor its class’s vtable found it.

Fields

module: &'static str

The module’s file name.

item: &'static str

The function’s name, including its namespace.

build: &'static str

The label of the loaded build.

scan: Option<Error>

Why the first pattern tried matched nothing, if there was one.

AlreadyHooked

The function is already hooked by this mod: a Hook for it is still alive.

Fields

module: &'static str

The module’s file name.

rva: u32

The function’s address relative to the module’s base.

Hook

The hooking engine failed to install, enable or disable a hook.

Fields

module: &'static str

The module’s file name.

rva: u32

The function’s address relative to the module’s base.

source: Error

The engine’s error.

UnsupportedPlatform

This platform is not supported; only Windows is.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
