Struct MemoryPlan 

pub struct MemoryPlan {
    pub arena_size: usize,
    pub assignments: HashMap<NodeId, BufferSlot>,
    pub schedule: Vec<NodeId>,
}

Complete memory plan for executing a graph.

Fields

arena_size: usize

Total arena size in bytes.

assignments: HashMap<NodeId, BufferSlot>

Buffer assignment: NodeId → offset within arena.

schedule: Vec<NodeId>

Node execution order (topological).

Implementations

impl MemoryPlan

pub fn total_unshared_bytes(&self) -> usize

Sum of all assigned buffer sizes (i.e. how much memory the plan would use if every node had its own slot). Useful for reporting how much the liveness-aware sharing saved.

pub fn bytes_saved(&self) -> usize

Bytes saved vs. naive “every node gets its own slot” — how much the liveness analysis bought you.

pub fn report(&self) -> String

Render the buffer plan as a one-line-per-node table for debugging — sorted by offset so adjacent buffers in memory are adjacent in the report (plan #87).

The output is parseable: <offset>\t<size>\t%<node_id>. Pipe through column -t for human display, or grep / awk it for scripted analysis.

Trait Implementations

impl Clone for MemoryPlan

fn clone(&self) -> MemoryPlan

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

Performs copy-assignment from source.

impl Debug for MemoryPlan

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

Formats the value using the given formatter.

impl From<&LirBufferPlan> for MemoryPlan

fn from(plan: &LirBufferPlan) -> Self

Converts to this type from the input type.

impl From<&MemoryPlan> for LirBufferPlan

fn from(plan: &MemoryPlan) -> Self
