Struct basic_dsp_vector::conv_types::ForeignRealConvolutionFunction

pub struct ForeignRealConvolutionFunction<T> where T: RealNumber {
    pub conv_function: extern fn(*const c_void, T) -> T,
    pub conv_data: usize,
    pub is_symmetric: bool,
}

A real function which can be constructed outside this crate.

Fields

conv_function: extern fn(*const c_void, T) -> T

The function

conv_data: usize

The data which is passed to the function.

Actual data type is a const* c_void, but Rust doesn't allow that because it's unsafe so we store it as usize and transmute it when necessary. Callers should make very sure safety is guaranteed.

is_symmetric: bool

Indicates whether this function is symmetric around 0 or not. Symmetry is defined as self.calc(x) == self.calc(-x).

Methods

impl<T> ForeignRealConvolutionFunction<T> where T: RealNumber

unsafe fn new(function: extern fn(*const c_void, T) -> T,
              function_data: *const c_void,
              is_symmetric: bool)
              -> Self

Creates a new real function
