Enum EngineError 

#[non_exhaustive]
pub enum EngineError {
    Apk(ApkError),
    Dex(DexError),
    Find(FindError),
    Rebuild(RebuildError),
    Smali(SmaliError),
    Axml(AxmlError),
    Arsc(ArscError),
    ClassNotFound {
        class: String,
        hint: String,
    },
    Query(String),
    BadDex {

    WorkerPanic(String),
}

Every error an Engine query can return.

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.

Apk(ApkError)

The APK (zip container) could not be opened or an entry not read.

Dex(DexError)

A DEX entry is malformed.

Find(FindError)

The reference search rejected the query or failed on a DEX.

Rebuild(RebuildError)

The minimal DEX of a class could not be rebuilt.

Smali(SmaliError)

A class could not be disassembled to smali.

Axml(AxmlError)

A binary XML document (such as the manifest) could not be decoded.

Arsc(ArscError)

resources.arsc could not be decoded.

ClassNotFound

No DEX of the APK defines the class.

hint (empty, or starting with : / ;) says why and what to try.

Fields

class: String

The class descriptor that was looked up.

hint: String

Appended to the message as is.

Query(String)

The query is invalid or names something the APK does not have; the message is meant for the user.

BadDex

A DEX entry is malformed in a way only noticed past its header.

Fields

dex: String

The entry (or logical DEX) name.

reason: String

What is wrong with it.

WorkerPanic(String)

A worker thread panicked; the payload names what it was processing.

Trait Implementations

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Error for EngineError

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.
