PlacementResourceLimits

Struct PlacementResourceLimits 

Source
pub struct PlacementResourceLimits {
    pub max_cpu_time_ms: u64,
    pub max_memory_bytes: usize,
    pub max_frame_payload_bytes: usize,
    pub max_stream_frames: usize,
    pub max_duration_ms: u64,
    pub max_rate_hz: u32,
    pub max_inflight_work: usize,
}
Expand description

Resource bounds enforced on a server placement before and during execution.

Combines compute bounds (CPU time, memory, inflight work) with the frame-shaping bounds shared with StreamRemoteLimits. A placement that would exceed any bound is refused rather than run unbounded; see PlacementResourceLimits::validate. The Default impl applies conservative defaults.

Fields§

§max_cpu_time_ms: u64

Maximum wall-clock CPU time, in milliseconds, allowed for the node.

§max_memory_bytes: usize

Maximum accounted payload memory, in bytes, across emitted frames.

§max_frame_payload_bytes: usize

Maximum encoded payload size, in bytes, allowed for a single frame.

§max_stream_frames: usize

Maximum number of data frames emitted for one placement.

§max_duration_ms: u64

Maximum stream duration, in milliseconds, before truncation.

§max_rate_hz: u32

Maximum stream rate, in hertz, used to derive the effective frame limit.

§max_inflight_work: usize

Maximum number of frames allowed in flight at once.

Implementations§

Source§

impl PlacementResourceLimits

Source

pub fn validate(self) -> Result<()>

Validates that every bound is positive and frame-consistent.

Returns an error when CPU time, memory, stream-size, or inflight-work is zero, or when the derived PlacementResourceLimits::remote_limits are themselves invalid.

Source

pub fn remote_limits(self) -> StreamRemoteLimits

Projects the frame-shaping subset of these limits onto a StreamRemoteLimits, mapping inflight-work to the inflight-frame bound.

Source

pub fn effective_stream_frame_limit(self) -> usize

Returns the effective per-stream frame limit after duration and rate bounds are folded into the configured stream-size limit.

Source

pub fn to_expr(self) -> Expr

Encodes these limits as a string-valued map Expr for placement reports.
