Struct JavaRuntime 

pub struct JavaRuntime(pub PathBuf);

Wrapper around a Java binary path for process execution

Tuple Fields

0: PathBuf

Implementations

impl JavaRuntime

pub fn new(path: PathBuf) -> Self

Creates a new JavaRuntime from a binary path

pub async fn execute( &self, arguments: Vec<String>, game_dir: &Path, ) -> JavaRuntimeResult<Child>

Spawns a Java process with the given arguments

Arguments

• arguments - Command-line arguments for the Java process
• game_dir - Working directory for the process

Returns

A handle to the spawned child process

Errors

Returns an error if the binary doesn’t exist or the spawn fails

pub async fn handle_io<D: Send + Sync>( &self, process: &mut Child, on_stdout: fn(&D, &[u8]) -> JavaRuntimeResult<()>, on_stderr: fn(&D, &[u8]) -> JavaRuntimeResult<()>, terminator: Receiver<()>, data: &D, ) -> JavaRuntimeResult<()>

Streams stdout/stderr from the process with custom handlers

This method handles I/O from the Java process, calling provided callbacks for stdout and stderr output. It continues until the process exits or the terminator signal is received.

Arguments

• process - Mutable reference to the child process
• on_stdout - Callback for stdout data
• on_stderr - Callback for stderr data
• terminator - Channel to signal early termination
• data - User data passed to callbacks

Returns

Ok(()) on clean exit, or error if the process exits with non-zero code

Note

Exit code -1073740791 (Windows forceful termination) is not treated as an error
