A Prefork Server. A server is used to fork() child processes.

Implementations

pub fn from_resource( resource: T, child_init: Box<dyn Fn(u32, T)>, num_processes: u32, ) -> Self

Create a server. The resource is passed to child processes. The child_init() function is called in each child process. There will be num_processes forked in a call to prefork().

pub fn prefork(&mut self) -> Result<Option<HashSet<Pid>>>

Fork multiple processes and return their process ids if this is the parent process.

Errors

Errors returned by fork() are propagated.

pub fn fork(&mut self) -> Result<Option<Pid>>

Fork a single process and return the process id if this is the parent process.
