Struct ObservationSet 

pub struct ObservationSet { /* private fields */ }

Deterministically ordered, path-addressed observations from one operation.

Implementations

impl ObservationSet

pub const fn new() -> Self

Creates an empty set.

pub fn insert( &mut self, path: impl Into<String>, value: ObservationValue, ) -> Result<(), ObservationError>

Inserts one uniquely named observation.

pub fn get(&self, path: &str) -> Option<&ObservationValue>

Looks up an observation by its stable path.

pub fn iter(&self) -> impl Iterator<Item = (&str, &ObservationValue)>

Iterates in stable path order.

pub fn len(&self) -> usize

Number of observations.

pub fn is_empty(&self) -> bool

Whether no observations are present.

pub fn prefixed(self, prefix: &str) -> Result<Self, ObservationError>

Adds a prefix to every path, preserving deterministic order.

pub fn extend(&mut self, other: Self) -> Result<(), ObservationError>

Extends this set, rejecting path collisions.
