Struct RlimitConfig 

pub struct RlimitConfig {
    pub max_open_files: Option<u64>,
    pub max_file_size_bytes: Option<u64>,
    pub disable_core_dumps: bool,
}

Declarative rlimit-based config.

Fields

max_open_files: Option<u64>

Maximum number of open file descriptors (RLIMIT_NOFILE).

Typical values:

• Some(1024) for “normal” processes
• Some(4096)/8192 for IO-heavy tasks
• None leaves the OS / parent limits unchanged.

max_file_size_bytes: Option<u64>

Maximum size of created files in bytes (RLIMIT_FSIZE).

When the process attempts to grow a file beyond this limit, the kernel typically delivers SIGXFSZ and the process terminates. None leaves the OS / parent limits unchanged.

disable_core_dumps: bool

Disable core dumps (RLIMIT_CORE = 0) when set to true.

This prevents large core files from being written for failing tasks. When false, the OS default / inherited core limit is preserved.

Implementations

impl RlimitConfig

pub fn is_empty(&self) -> bool

Returns true if no explicit limits are configured.

Trait Implementations

impl Default for RlimitConfig

fn default() -> RlimitConfig

Returns the “default value” for a type.
