Fields of Map

from: Vec<Source>

the sources we are mapping from

function: String

the name of the built-in 'Value -> Option Value' function that will be called each time the source produces a value. If the function returns None then no value will be produced by the source, otherwise the returned value will be produced. You must define the function in one of the scripts imported by the view. Note, if the wrapped source is a group, and the function is an aggregate function then it will operate on all the values (e.g. sum, mean, ewma, etc ...), otherwise it will operate on the first value in the group to update.

Trait Implementations

impl Clone for Source

pub fn clone(&self) -> Source

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

impl FromStr for Source

type Err = Error

The associated error which can be returned from parsing.

pub fn from_str(s: &str) -> Result<Self, Self::Err>
