pub enum CostEstimateSource {
    Measured,
    AreaFallback,
    FixedDefault,
}

AreaFallback

Derived from area-based fallback (cells * cost_per_cell).

FixedDefault

Trait Implementations

impl Clone for CostEstimateSource

fn clone(&self) -> CostEstimateSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CostEstimateSource

impl Debug for CostEstimateSource

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

Formats the value using the given formatter.

impl Default for CostEstimateSource

fn default() -> CostEstimateSource

Returns the “default value” for a type.

impl Eq for CostEstimateSource

impl PartialEq for CostEstimateSource

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