Struct jerk::jvm::Library

pub struct Library { /* fields omitted */ }

Represents a loaded jvm.dll or libjvm.so instance.

Methods

impl Library

pub fn get() -> Result<Library, LoadError>

Get an instance of the library by... whatever logic jerk feels like. This currently means searching in this order:

• Already loaded symbols, in case Java is hosting us (.jar entry point like on Android) instead of us hosting Java
• %JAVA_HOME%, if set
• Various JDK locations that could totally have been set as %JAVA_HOME%

pub fn from_already_loaded() -> Result<Library, LoadError>

Reference the already loaded JVM library.

pub fn from_system() -> Result<Library, LoadError>

This is supported on non-Android only.

Load a JVM library from wherever.

pub fn from_java_home(
    java_home: &impl AsRef<Path> + ?Sized
) -> Result<Library, LoadError>

This is supported on non-Android only.

Load a JVM library from a specific %JAVA_HOME%.

Arguments

• java_home - this should be %JAVA_HOME% or similar.

pub fn from_library_path(
    libjvm: &impl AsRef<Path> + ?Sized
) -> Result<Library, LoadError>

This is supported on non-Android only.

Load a JVM library from a specific path.

Arguments

• libjvm - this should be a path to jvm.dll / libjvm.so

pub fn create_java_vm(
    &self,
    java_vm_options: Vec<String>
) -> Result<*mut JavaVM, JniError>
