Struct LatencyTable 

pub struct LatencyTable {
    pub op_latencies: HashMap<String, f64>,
    pub size_scale: f64,
}

Lookup table mapping (operation_name, input_size) → latency in milliseconds.

The default constructor populates a set of representative estimates.

Fields

op_latencies: HashMap<String, f64>

Raw latency data: key = operation name, value = base latency (ms).

size_scale: f64

Scale factor applied per input-size unit.

Implementations

impl LatencyTable

pub fn new() -> Self

Create a new table with default hardware latency estimates.

Values are representative of a mid-range mobile CPU at 224×224 feature map.

pub fn latency_of(&self, op: &str, input_size: usize) -> f64

Latency for a single operation given input_size (e.g., HWC).

Uses a simple linear model: latency = base + size_scale * input_size.

pub fn total_latency(&self, arch: &[(String, usize)]) -> f64

Total latency for a sequence of (operation_name, input_size) pairs.

Trait Implementations

impl Clone for LatencyTable

fn clone(&self) -> LatencyTable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LatencyTable

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

Formats the value using the given formatter.

impl Default for LatencyTable

fn default() -> Self

Returns the “default value” for a type.
