Trait IsConstantKernel

Source 
pub trait IsConstantKernel: VTable {
    // Required method
    fn is_constant(
        &self,
        array: &Self::Array,
        opts: &IsConstantOpts,
    ) -> VortexResult<Option<bool>>;
}

Required Methods§

Source

fn is_constant( &self, array: &Self::Array, opts: &IsConstantOpts, ) -> VortexResult<Option<bool>>

  • All values are valid
  • array.len() > 1

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.
