Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_cpu_time: Option<ProcLimit>

Implementations

impl ProcLimits

pub fn read_self() -> Result<Self>

Reads the current process’s resource limits from /proc/self/limits.

Errors

Returns an error if any IO operation failed.

Returns an error if the file format is invalid.

pub fn read_process(pid: pid_t) -> Result<Self>

Reads a process’s resource limits from /proc/[pid]/limits.

Errors

Returns an error if pid is negative.

Returns an error if any IO operation failed.

Returns an error if the file format is invalid.

Trait Implementations

impl Clone for ProcLimits

fn clone(&self) -> ProcLimits

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProcLimits

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ProcLimits

fn default() -> ProcLimits

Returns the “default value” for a type.
