Struct Budget 

pub struct Budget {
    pub slice: String,
    pub memory_max: Option<u64>,
    pub memory_in_use: u64,
    pub admission: AdmissionPolicy,
    pub held: bool,
    pub mirror_memory: u64,

    pub shell_memory: Vec<ShellMemory>,
    pub host: Option<HostBudget>,
    pub cpu: Option<CpuBudget>,
    pub slice_cpus: Option<u64>,
}

The memory budget runners and the mirror share, in bytes.

Fields

slice: String

The systemd slice runner containers run in.

memory_max: Option<u64>

The slice’s MemoryMax; None when it is unlimited.

memory_in_use: u64

Memory the running containers reserve: the runners’ caps, or under measured admission the larger of each runner’s predicted peak and its last sampled memory, and the caps of the seed containers, shells and the mirror.

admission: AdmissionPolicy

What a new runner must fit in beside them.

held: bool

Under measured admission, whether the slice is at the high-water mark, so no runner starts.

mirror_memory: u64

The mirror’s part of memory_in_use: its cap while it is enabled or still running, else 0.

seed_memory: Vec<SeedMemory>

The seed containers’ part of memory_in_use, one per profile that reseeds, by profile name.

shell_memory: Vec<ShellMemory>

The shells’ part of memory_in_use, one per shell open in a record, by job.

host: Option<HostBudget>

What the host’s memory leaves runners beside its other programs, from a recent reading of it; absent without one, and from a daemon before it read the host.

cpu: Option<CpuBudget>

The CPU budget, under [host] cpu_overcommit. Absent without one, and from a daemon before CPU admission.

slice_cpus: Option<u64>

The CPUs the slice may use, in millicores: its AllowedCPUs or the host’s, less under a lower CPUQuota, whether or not a CPU budget admits runners. The runners’ CPU limits are quotas that may add up past it. Absent when it could not be read, and from a daemon before it said.

Implementations

impl Budget

pub fn admission_note(&self) -> Option<&'static str>

How runners are admitted, as clients add it to the budget’s line: nothing under caps, else by predicted peaks, and why nothing starts while the slice is at the high-water mark.
