Constant methods for crate::shape::HistogramCostExtractor
Required Methods§
fn as_raw_HistogramCostExtractor(&self) -> *const c_void
Provided Methods§
fn get_n_dummies(&self) -> Result<i32>
fn get_default_cost(&self) -> Result<f32>
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.
