Struct dlt_core::dlt::FixedPoint

pub struct FixedPoint {
    pub quantization: f32,
    pub offset: FixedPointValue,
}

The following equation defines the relation between the logical value (log_v) and the physical value (phy_v), offset and quantization: log_v = phy_v * quantization + offset

• phy_v is what we received in the dlt message
• log_v is the real value example: the degree celcius is transmitted, quantization = 0.01, offset = -50 now the transmitted value phy_v = (log_v - offset)/quantization = 7785

The width depends on the TYLE value * i32 bit if Type Length (TYLE) equals 1,2 or 3 * i64 bit if Type Length (TYLE) equals 4 * i128 bit if Type Length (TYLE) equals 5 (unsupported)

Fields

quantization: f32

offset: FixedPointValue

Trait Implementations

impl Clone for FixedPoint

fn clone(&self) -> FixedPoint

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FixedPoint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<FixedPoint> for FixedPoint

fn eq(&self, other: &FixedPoint) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FixedPoint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.
