Methods

impl StatsRecord

pub fn new<S: Into<Option<String>>, S2: Into<Option<String>>, D: DescriptiveStats>(
    stream_id: S,
    metric: S2,
    desc: D
) -> Self

pub fn from_reader(
    read: &mut dyn Read
) -> Result<HashMap<String, Box<dyn DescriptiveStats>>, Box<dyn Error>>

Produces a hash map of descriptive statistics from read keyed by metric name.
