Struct JavaRun 

pub struct JavaRun { /* private fields */ }

A builder for a java command that can be invoked.

If you need to customize the java command beyond what is provided here, you can use the JavaRun::command() method to get a Command that can be further customized with additional arguments.

Documentation on java options are based on https://dev.java/learn/jvm/tools/core/java/.

Implementations

impl JavaRun

pub fn new() -> Self

Creates a new JavaRun instance with default values, which can be further customized using the builder methods.

pub fn run(&self) -> Result<ExitStatus>

Executes the java command based on this JavaRun instance.

pub fn command(&self) -> Result<Command>

Returns a Command based on this JavaRun instance that can be inspected or customized before being executed.

pub fn java_home<P: AsRef<OsStr>>(&mut self, java_home: P) -> &mut Self

Override the default JAVA_HOME path.

If not set, the default path is found using the JAVA_HOME env var.

pub fn class_path<S: AsRef<OsStr>>(&mut self, class_path: S) -> &mut Self

Specify where to find user class files.

If no class paths are provided, the current directory will be used.

pub fn enable_preview_features( &mut self, enable_preview_features: bool, ) -> &mut Self

Enable or disable preview language features.

pub fn main_class<S: AsRef<OsStr>>(&mut self, class: S) -> &mut Self

Specify the main class to launch when running the java command.

Note that this and the jar_file are mutually exclusive; only one can be chosen at a time.

pub fn jar_file<P: AsRef<OsStr>>(&mut self, jar_file: P) -> &mut Self

Specify the JAR file to run with the java command.

Note that this and the main_class are mutually exclusive; only one can be chosen at a time.

pub fn arg<S: AsRef<OsStr>>(&mut self, arg: S) -> &mut Self

Add an argument to be passed to the main class being run by java.

pub fn args<I>(&mut self, args: I) -> &mut Self

where I: IntoIterator, I::Item: AsRef<OsStr>,

Adds multiple arguments to be passed to the main class being run by java.
