latency_ms: f64

Estimated latency (milliseconds)

custom: HashMap<String, f64>

Custom cost metrics

Implementations

impl OperationCost

pub fn new() -> Self

Create a new operation cost with default values.

pub fn compute_only(flops: f64) -> Self

Create an operation cost with only computational cost.

pub fn compute_and_memory(flops: f64, memory_bytes: f64) -> Self

Create an operation cost with computational and memory cost.

pub fn with_custom(self, key: impl Into<String>, value: f64) -> Self

Add a custom cost metric.

pub fn add(&self, other: &OperationCost) -> OperationCost

Combine two costs (for sequential operations).

pub fn max(&self, other: &OperationCost) -> OperationCost

Get the maximum cost (for parallel operations).

Trait Implementations

impl Clone for OperationCost

fn clone(&self) -> OperationCost

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperationCost

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

Formats the value using the given formatter.

impl Default for OperationCost

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OperationCost

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for OperationCost

fn eq(&self, other: &OperationCost) -> 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 Serialize for OperationCost

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
