Enum ChannelSelector 

pub enum ChannelSelector {
    Name(String),
    NameInGroup {
        name: String,
        data_group: usize,
        channel_group: usize,
    },
    Position {
        data_group: usize,
        channel_group: usize,
        index: usize,
    },
}

How a channel is picked out of a file by Mf4File::filter.

ChannelSelector::from("Speed") is the common case; the other two variants exist for names that several channels share.

Variants

Name(String)

The channel with this name, which must be unique in the file.

A name carried by more than one channel is an error rather than a silent pick of the first: a master channel called t exists in every group, and quietly filtering the wrong group’s copy of it is precisely the kind of plausible-but-wrong answer this crate tries not to give. Disambiguate with ChannelSelector::NameInGroup or ChannelSelector::Position.

NameInGroup

The channel with this name inside one specific channel group.

Fields

name: String

Channel name.

data_group: usize

Index of the data group.

channel_group: usize

Index of the channel group within that data group.

Position

The channel at an exact position, regardless of its name.

Fields

data_group: usize

Index of the data group.

channel_group: usize

Index of the channel group within that data group.

index: usize

Index of the channel within that channel group.
