Struct Sources 

pub struct Sources<'a>(Vec<Source<'a>>);

A source mapping defines how multiple sources are transformed and combined into a single measurement stream.

When built, it produces a list of source-transform pairs. If the caller receives a measurement from source “X”, they should then apply the transform associated with “X” to the measurement.

Tuple Fields

0: Vec<Source<'a>>

Implementations

impl<'a> Sources<'a>

pub fn new_direct(source: Cow<'a, str>) -> Self

pub fn build( self, legend: &mut Legend, ) -> Result<Vec<(Cow<'a, str>, Transform)>>

Builds the source mapping into a list of source-transform pairs.

See the type-level documentation for more details.

pub fn build_mut( self, legend: &mut Legend, ) -> Result<Vec<(Cow<'a, str>, TransformMut)>>

Builds the source mapping into a list of source-transform pairs.

Unlike build, this results in mutable transforms, which can apply stateful transformations to the measurements.

See the type-level documentation for more details.

Trait Implementations

impl<'de: 'a, 'a> Deserialize<'de> for Sources<'a>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
