Struct PlacementResourceLimits 

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,
}

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

impl PlacementResourceLimits

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.

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.

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.

pub fn to_expr(self) -> Expr

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

Trait Implementations

impl Clone for PlacementResourceLimits

fn clone(&self) -> PlacementResourceLimits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PlacementResourceLimits

impl Debug for PlacementResourceLimits

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

Formats the value using the given formatter.

impl Default for PlacementResourceLimits

fn default() -> Self

Returns the “default value” for a type.

impl Eq for PlacementResourceLimits

impl PartialEq for PlacementResourceLimits

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