Trait CommandOpenFileLimitExt 

pub trait CommandOpenFileLimitExt {
    // Required method
    fn set_open_file_limit(&mut self, limit: u64) -> Result<(), Error>;
}

Available on Unix only.

Extension trait for setting a command’s open-file limit before it runs.

Required Methods

fn set_open_file_limit(&mut self, limit: u64) -> Result<(), Error>

Arranges for the command to set its soft RLIMIT_NOFILE to limit, or to its hard limit if that is lower, after it is forked and before it runs its program.

Errors

None here: a child that cannot set the limit fails its spawn.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
