Struct Limits 

pub struct Limits {
    pub wall_timeout: Duration,
    pub max_response_bytes: u32,
    pub max_stderr_bytes: u64,
    pub address_space_bytes: u64,
    pub cpu_seconds: u64,
    pub file_size_bytes: u64,
    pub max_processes: u64,
}

Resource and output limits for one adapter class.

Fields

wall_timeout: Duration

Wall-clock ceiling enforced by the parent.

max_response_bytes: u32

Ceiling on the response frame payload, checked against the declared length before allocation.

max_stderr_bytes: u64

Ceiling on stderr bytes, drained and counted concurrently.

address_space_bytes: u64

RLIMIT_AS for the child, in bytes.

cpu_seconds: u64

RLIMIT_CPU for the child, in seconds.

file_size_bytes: u64

RLIMIT_FSIZE for the child, in bytes. Caps regular-file growth inside the jail. Stdout is a pipe, so the response cap above is enforced by the parent instead.

max_processes: u64

RLIMIT_NPROC for the child. An absolute cap on the process and thread count of the mapped real user id, so a compromised adapter cannot fork-bomb the host. The default is a modest absolute value: the shipped adapter spawns nothing, so on a host where the user already runs more tasks than the cap, every fork from the adapter fails, which is the intent.

Trait Implementations

impl Default for Limits

fn default() -> Limits

Returns the “default value” for a type.
