Struct ProgramStats 

pub struct ProgramStats {
    pub node_count: usize,
    pub region_count: u32,
    pub call_count: u32,
    pub opaque_count: u32,
    pub top_level_regions: u32,
    pub static_storage_bytes: u64,
    pub instruction_count: u64,
    pub memory_op_count: u64,
    pub atomic_op_count: u64,
    pub control_flow_count: u64,
    pub register_pressure_estimate: u32,
    pub capability_bits: u32,
}

Aggregated statistics computed from a single walk of a Program.

This struct is cached inside Program via a std::sync::OnceLock so that planning passes (execution plan, capability scan, provenance, fusion) can read constant-time summaries instead of re-walking the IR.

Fields

node_count: usize

Total statement-node count (includes nested children).

region_count: u32

Number of Node::Region nodes in the full tree.

call_count: u32

Number of Expr::Call expressions.

opaque_count: u32

Number of Node::Opaque nodes and Expr::Opaque expressions.

top_level_regions: u32

Number of top-level Node::Region wrappers in program.entry().

static_storage_bytes: u64

Sum of statically-known buffer byte sizes.

instruction_count: u64

Estimated scalar/vector IR instruction count.

memory_op_count: u64

Number of explicit memory operations (loads, stores, async copies).

atomic_op_count: u64

Number of atomic read-modify-write expressions.

control_flow_count: u64

Number of control-flow operations.

register_pressure_estimate: u32

Coarse register pressure estimate from simultaneously named SSA-ish values.

capability_bits: u32

Bitmask of capability requirements (see CAP_* constants).

Implementations

impl ProgramStats

pub fn subgroup_ops(&self) -> bool

True when the program uses subgroup operations.

pub fn f16(&self) -> bool

True when the program uses IEEE-754 binary16 values.

pub fn bf16(&self) -> bool

True when the program uses bfloat16 values.

pub fn f64(&self) -> bool

True when the program uses IEEE-754 binary64 values.

pub fn async_dispatch(&self) -> bool

True when the program requires async dispatch semantics.

pub fn indirect_dispatch(&self) -> bool

True when the program requires indirect dispatch support.

pub fn tensor_ops(&self) -> bool

True when the program uses tensor / tensor-core operand types.

pub fn trap(&self) -> bool

True when the program uses Node::Trap.

Trait Implementations

impl Clone for ProgramStats

fn clone(&self) -> ProgramStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProgramStats

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

Formats the value using the given formatter.

impl Default for ProgramStats

fn default() -> ProgramStats

Returns the “default value” for a type.

impl PartialEq for ProgramStats

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

impl Copy for ProgramStats

impl Eq for ProgramStats

impl StructuralPartialEq for ProgramStats
