Struct ChannelGroup 

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

High level wrapper for a channel group.

The struct references raw channel group data and provides ergonomic access to its metadata and channels without decoding any actual samples.

Implementations

impl<'a> ChannelGroup<'a>

pub fn new( raw_data_group: &'a RawDataGroup, raw_channel_group: &'a RawChannelGroup, mmap: &'a [u8], ) -> Self

Create a new ChannelGroup referencing the underlying raw blocks.

Arguments

• raw_data_group - Parent data group containing this channel group
• raw_channel_group - The raw channel group block
• mmap - Memory mapped file backing all data

Returns

A ChannelGroup handle with no decoded data.

pub fn name(&self) -> Result<Option<String>>

Retrieve the human readable group name.

pub fn comment(&self) -> Result<Option<String>>

Retrieve the group comment if present.

pub fn source(&self) -> Result<Option<SourceInfo>>

Get the acquisition source information if available.

pub fn channels(&self) -> Vec<Channel<'a>>

Build all Channel objects for this group.

No channel data is decoded; the returned channels simply reference the raw blocks.

pub fn raw_data_group(&self) -> &RawDataGroup

Get the raw data group (for internal use)

pub fn raw_channel_group(&self) -> &RawChannelGroup

Get the raw channel group (for internal use)

pub fn mmap(&self) -> &[u8]

Get the memory mapped data (for internal use)
