Struct HostBudget 

pub struct HostBudget {
    pub memory: HostMemory,
    pub limit: u64,
    pub spare: u64,
    pub stalled: bool,
}

What the host’s memory leaves the runners (ADR 0055). New runners fit in the lower of MemoryMax and limit; running ones are never stopped for it.

Fields

memory: HostMemory

The reading it comes from.

limit: u64

What the slice may hold now: what its runners hold without page cache plus the host’s MemAvailable, less a margin kept free for the host’s page cache.

spare: u64

What that leaves new runners beside what the running ones reserve, in bytes.

stalled: bool

Whether the host’s tasks stall for memory (full pressure), so no runner starts until they stop.

Implementations

impl HostBudget

pub fn line(&self) -> String

The host’s line as clients show it, such as host: 31G of 64G available, 1.5% stalled for memory; leaves the slice 40G or, while it stalls, …; stalling, so no runner starts; with programs outside the slice large enough to name, …; programs outside CI hold 30G, most java 9.3G (HostMemory::outside_line).
