Struct jni::InitArgsBuilder

pub struct InitArgsBuilder { /* private fields */ }

Builder for JavaVM InitArgs.

This API requires “invocation” feature to be enabled, see “Launching JVM from Rust”.

Implementations

impl InitArgsBuilder

pub fn new() -> Self

Create a new default InitArgsBuilder

pub fn option(self, opt_string: &str) -> Self

Add an option to the init args

The vfprintf, abort, and exit options are unsupported at this time.

pub fn version(self, version: JNIVersion) -> Self

Set JNI version for the init args

Default: V8

pub fn ignore_unrecognized(self, ignore: bool) -> Self

Set the ignoreUnrecognized init arg flag

If ignoreUnrecognized is true, JavaVM::new ignores all unrecognized option strings that begin with “-X” or “_”. If ignoreUnrecognized is false, JavaVM::new returns Err as soon as it encounters any unrecognized option strings.

Default: false

pub fn build(self) -> Result<InitArgs, JvmError>

Build the InitArgs

This will check for internal nulls in the option strings and will return an error if one is found.

pub fn options(&self) -> Vec<String>

Returns collected options
