Struct sttp::transport::SignalIndexCache

pub struct SignalIndexCache { /* private fields */ }

Represents a mapping of 32-bit runtime IDs to 128-bit globally unique measurement IDs. The class additionally provides reverse lookup and an extra mapping to human-readable measurement keys.

Implementations

impl SignalIndexCache

pub fn new() -> SignalIndexCache

Creates a new, empty SignalIndexCache.

pub fn contains(&self, signal_index: i32) -> bool

Determines if the specified signalindex exists with the SignalIndexCache.

pub fn signal_id(&self, signal_index: i32) -> Uuid

Returns the signal ID Guid for the specified signalindex in the SignalIndexCache.

pub fn signal_ids(&self) -> HashSet<Uuid>

Gets a set for all the Guid values found in the SignalIndexCache.

pub fn source(&self, signal_index: i32) -> &str

Returns the Measurement source string for the specified signalindex in the SignalIndexCache.

pub fn id(&self, signal_index: i32) -> u64

Returns the Measurement integer ID for the specified signalindex in the SignalIndexCache.

pub fn record(&self, signal_index: i32) -> (Uuid, &str, u64, bool)

Record returns the key Measurement values, signal ID Guid, source string, and integer ID and a final boolean value representing find success for the specified signalindex in the SignalIndexCache.

pub fn signal_index(&self, signal_id: Uuid) -> i32

Returns the signal index for the specified signal ID Guid in the SignalIndexCache.

pub fn count(&self) -> u32

Gets the number of Measurement records that can be found in the SignalIndexCache.

pub fn decode(&mut self, buffer: &[u8]) -> Result<Uuid, Box<dyn Error>>

Parses a SignalIndexCache from the specified byte buffer received from a DataPublisher.
