Struct StateSeriesView 

pub struct StateSeriesView<'a> { /* private fields */ }

A lightweight immutable view over a canonical specification and state slice.

Both Copy and Clone copy only two references. Neither operation clones a specification, state, payload, or vector allocation. The private constructor ensures every public view originates from a validated StateSeries.

Implementations

impl<'a> StateSeriesView<'a>

pub fn schema(self) -> &'a SystemStateSchema

Returns the canonical specification shared by the borrowed states.

pub fn len(self) -> usize

Returns the number of borrowed states.

pub fn is_empty(self) -> bool

Reports whether the view contains no states.

pub fn state_at(self, position: usize) -> Option<&'a SystemState>

Returns a state by zero-based view position.

pub fn first_state(self) -> Option<&'a SystemState>

Returns the earliest borrowed state, or None for an empty view.

pub fn last_state(self) -> Option<&'a SystemState>

Returns the latest borrowed state, or None for an empty view.

pub fn as_state_slice(self) -> &'a [SystemState]

Returns the complete immutable state slice.

pub fn iter(self) -> Iter<'a, SystemState>

Returns an iterator over borrowed states in increasing iteration order.

Trait Implementations

impl<'a> Clone for StateSeriesView<'a>

fn clone(&self) -> StateSeriesView<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for StateSeriesView<'a>

impl Debug for StateSeriesView<'_>

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats bounded structural context without traversing payload values.

impl<'a> IntoIterator for StateSeriesView<'a>

fn into_iter(self) -> Self::IntoIter

Iterates over the borrowed states without cloning payloads.

type Item = &'a SystemState

The type of the elements being iterated over.

type IntoIter = Iter<'a, SystemState>

Which kind of iterator are we turning this into?
