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.

AlreadyLoaded

The dynamic linker has already loaded the jvm.

LoadingSharedObjectFailed

The dynamic linker failed to load the jvm shared object.

Fields

path: String

relative path to the shared object.

error: Box<dyn Error>

platform-specific error

JNICreateJavaVmNotFound

The dynamic linker could not find the JNI_CreateJavaVM symbol in the shared object.

Fields

path: String

relative path to the shared object.

error: Box<dyn Error>

platform-specific error

JNIGetCreatedJavaVMsNotFound

The dynamic linker could not find the JNI_GetCreatedJavaVMs symbol in the shared object.

Fields

path: String

relative path to the shared object.

error: Box<dyn Error>

platform-specific error

UnknownJavaHomeLayout

The layout of the java installation was not recognized.

IOError(Error)

I/O Error while determining the layout of the java installation.

EnvironmentVariableError(VarError)

The environment variable JAVA_HOME is invalid

Trait Implementations

impl Debug for LoadFromJavaHomeError

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

Formats the value using the given formatter.

impl Display for LoadFromJavaHomeError

Available on crate features loadjvm and std only.

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

Formats the value using the given formatter.

impl Error for LoadFromJavaHomeError

Available on crate features loadjvm and std only.

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.

impl From<LoadFromJavaHomeError> for String

Available on crate features loadjvm and std only.

Provided for backwards compile-compat with ? operator, all errors used to be just Strings, which was perhaps not the wisest choice.

fn from(value: LoadFromJavaHomeError) -> Self

Converts to this type from the input type.

impl From<LoadFromJavaHomeFolderError> for LoadFromJavaHomeError

Available on crate features loadjvm and std only.

fn from(value: LoadFromJavaHomeFolderError) -> Self

Converts to this type from the input type.

impl From<LoadFromLibraryError> for LoadFromJavaHomeError

Available on crate features loadjvm and std only.

fn from(value: LoadFromLibraryError) -> Self

Converts to this type from the input type.
