Datatype

comnum_spec::io

Struct Datatype 

Source 
pub struct Datatype {
    pub complex: bool,
    pub scalar: Scalar,
    pub big_endian: bool,
}
Expand description

A sample format of SigMF: [c|r][f32|f64|i32|i16|i8|u32|u16|u8][_le|_be] (the 8-bit types without endianness).

Integer samples are converted to floating point without scaling; the unsigned types are centred by $2^{b-1}$ (128 for cu8), as the reference implementation sigmf-python does. SigMF::full_scale gives the scale of its autoscale.

Fields§

§complex: bool

Complex (interleaved I and Q) or real.

§scalar: Scalar

The type of a component.

§big_endian: bool

Big-endian components.
