Struct IoLimits 

#[non_exhaustive]
pub struct IoLimits {
    pub weight: Option<u16>,
}

IO controller limits (io.weight). Per-device throughput caps (io.max) are intentionally not surfaced here — the per-device interface needs major:minor device-id lookup which has no in-tree consumer; surface it when a concrete use case lands.

Set via CgroupDef::io_weight. Construct directly only when copying an IoLimits across CgroupDefs — the builder method is the preferred entry point because it routes the per-knob value through the framework’s validation seam at apply_setup.

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.

weight: Option<u16>

io.weight relative-share weight (range 1..=10000, default 100). None leaves the kernel default in place.

Trait Implementations

impl Clone for IoLimits

fn clone(&self) -> IoLimits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IoLimits

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

Formats the value using the given formatter.

impl Default for IoLimits

fn default() -> IoLimits

Returns the “default value” for a type.

impl PartialEq for IoLimits

fn eq(&self, other: &IoLimits) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
