Struct ChannelObserverRef 

pub struct ChannelObserverRef<'a> { /* private fields */ }

Represents an immutable reference to a channel observer in an MDF file.

A channel observer holds all sample data for a specific channel and provides methods to access channel values and engineering values.

Implementations

impl<'a> ChannelObserverRef<'a>

pub fn get_nof_samples(&self) -> usize

Gets the number of samples in this channel observer.

pub fn get_channel_value(&self, sample: usize) -> Option<f64>

Gets the channel value (raw, unscaled) for a specific sample.

Arguments

• sample - The sample index (0-based)

Returns

Returns Some(value) if the sample is valid, None otherwise.

pub fn get_eng_value(&self, sample: usize) -> Option<f64>

Gets the engineering value (scaled) for a specific sample.

Arguments

• sample - The sample index (0-based)

Returns

Returns Some(value) if the sample is valid, None otherwise.

pub fn is_valid(&self, sample: usize) -> bool

Checks if a specific sample is valid.

Arguments

• sample - The sample index (0-based)

Returns

Returns true if the sample is valid, false otherwise.

pub fn get_all_channel_values(&self) -> Vec<Option<f64>>

Gets all channel values (raw, unscaled) for all samples.

Returns

Returns a vector of Option<f64> where None indicates an invalid sample.

pub fn get_all_eng_values(&self) -> Vec<Option<f64>>

Gets all engineering values (scaled) for all samples.

Returns

Returns a vector of Option<f64> where None indicates an invalid sample.
