Approximate an object
Required Associated Types§
Sourcetype Approximation
type Approximation
The approximation of the object
Required Methods§
Sourcefn approx_with_cache(
self,
tolerance: impl Into<Tolerance>,
cache: &mut Self::Cache,
) -> Self::Approximation
fn approx_with_cache( self, tolerance: impl Into<Tolerance>, cache: &mut Self::Cache, ) -> Self::Approximation
Approximate the object, using the provided cache
This is a lower-level method that allows some degree of control over
caching. Callers might consider using Approx::approx instead.
Provided Methods§
Sourcefn approx(self, tolerance: impl Into<Tolerance>) -> Self::Approximation
fn approx(self, tolerance: impl Into<Tolerance>) -> Self::Approximation
Approximate the object
tolerance defines how far the approximation is allowed to deviate from
the actual object.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
