Enum FeatureId 

pub enum FeatureId<'a> {
    StringValue(&'a str),
    UintValue(u64),
    IntValue(i64),
    DoubleValue(f64),
}

The ID of a feature in a source, as the source’s data gives it.

The map compares feature IDs as text. A number names the same feature as the string of its shortest decimal form, so 7, 7.0, and “7” name one feature.

See mln_feature_id in the C API reference.

Variants

StringValue(&'a str)

UintValue(u64)

IntValue(i64)

DoubleValue(f64)

A finite number.
