Struct FeatureDescriptor 

pub struct FeatureDescriptor {
    pub name: String,
    pub unit: Option<String>,
    pub transform: Option<String>,
    pub constraint: Option<FeatureConstraint>,
    pub metadata: BTreeMap<String, String>,
}

Semantic description of one ordered input feature.

Fields

name: String

Stable feature name.

unit: Option<String>

Optional unit such as seconds or bytes.

transform: Option<String>

Optional caller-defined transform identifier.

constraint: Option<FeatureConstraint>

Optional numeric domain.

metadata: BTreeMap<String, String>

Bounded semantic metadata. Ordered storage makes hashing canonical.

impl FeatureDescriptor

pub fn new(name: impl Into<String>) -> Result<Self, RillError>
