Helper for extracting a DBC signal value from CAN frame data.

is_signed: bool

min: f64

max: f64

Implementations

impl SignalValueExtractor

fn from_dbc_signal(signal: &Signal) -> Result<Self>

fn extract_raw_unchecked(&self, data: &[u8]) -> Option<f64>

pub fn extract_unchecked(&self, data: &[u8]) -> Option<f64>

Extracts the unchecked signal value from the CAN frame data.

This does not check for min/max limits and just returns the raw value multiplied by the factor and added to the offset. It still returns None if the resulting value is non-finite (NaN or infinity). This is possible if the raw value combined with the factor and offset results in a value that is large enough to spill over to infinity in floating point math.

See Self::extract for a version that also checks the min/max limits.

pub fn extract(&self, data: &[u8]) -> Option<f64>

Extracts the signal value from the CAN frame data.

Returns None if the value is out of the min/max limits or if the value is non-finite (NaN or infinity). See Self::extract_unchecked for a version that does not check the min/max limits.

Trait Implementations
