Mutable methods for crate::img_hash::ImgHashBase

Required Methods§

Source

fn as_raw_mut_ImgHashBase(&mut self) -> *mut c_void

Provided Methods§

Source

fn compute( &mut self, input_arr: &impl ToInputArray, output_arr: &mut impl ToOutputArray, ) -> Result<()>

Computes hash of the input image

§Parameters
  • inputArr: input image want to compute hash value
  • outputArr: hash of the image

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.
