Struct aws_sdk_greengrassv2::types::SystemResourceLimits

#[non_exhaustive]
pub struct SystemResourceLimits {
    pub memory: i64,
    pub cpus: f64,
}

Contains information about system resource limits that the IoT Greengrass Core software applies to a component's processes. For more information, see Configure system resource limits for components.

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.

memory: i64

The maximum amount of RAM, expressed in kilobytes, that a component's processes can use on the core device.

cpus: f64

The maximum amount of CPU time that a component's processes can use on the core device. A core device's total CPU time is equivalent to the device's number of CPU cores. For example, on a core device with 4 CPU cores, you can set this value to 2 to limit the component's processes to 50 percent usage of each CPU core. On a device with 1 CPU core, you can set this value to 0.25 to limit the component's processes to 25 percent usage of the CPU. If you set this value to a number greater than the number of CPU cores, the IoT Greengrass Core software doesn't limit the component's CPU usage.

Implementations

impl SystemResourceLimits

pub fn memory(&self) -> i64

The maximum amount of RAM, expressed in kilobytes, that a component's processes can use on the core device.

pub fn cpus(&self) -> f64

The maximum amount of CPU time that a component's processes can use on the core device. A core device's total CPU time is equivalent to the device's number of CPU cores. For example, on a core device with 4 CPU cores, you can set this value to 2 to limit the component's processes to 50 percent usage of each CPU core. On a device with 1 CPU core, you can set this value to 0.25 to limit the component's processes to 25 percent usage of the CPU. If you set this value to a number greater than the number of CPU cores, the IoT Greengrass Core software doesn't limit the component's CPU usage.

impl SystemResourceLimits

pub fn builder() -> SystemResourceLimitsBuilder

Creates a new builder-style object to manufacture SystemResourceLimits.

Trait Implementations

impl Clone for SystemResourceLimits

fn clone(&self) -> SystemResourceLimits

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SystemResourceLimits

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

Formats the value using the given formatter.

impl PartialEq for SystemResourceLimits

fn eq(&self, other: &SystemResourceLimits) -> 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.
