Struct StateStreamConfig 

pub struct StateStreamConfig { /* private fields */ }

Configuration for one independently sampled logical output stream.

Field names are exact keys from the run’s SystemStateSchema. Their input order is irrelevant: the encoder writes them in canonical template order. Chunk targets are rollover thresholds, while individual-file streams seal every record immediately. The queue byte limit is strict in either layout.

Implementations

impl StateStreamConfig

pub fn new<I, K>( name: impl Into<String>, fields: I, sampling_interval: SamplingInterval, storage: Option<StateStreamStorage>, ) -> Self

where I: IntoIterator<Item = K>, K: Into<String>,

Creates a stream whose relative output directory initially equals its logical name.

storage == None inherits writer-wide storage. Non-zero types make explicit limits valid by construction. Names, paths, duplicate fields, and state-key membership are validated together by SystemStateWriterBuilder::create_new_recording.

pub fn with_relative_directory(self, directory: impl Into<String>) -> Self

Overrides the stream’s relative directory beneath the run root.

Absolute paths, empty paths, and . or .. components are rejected at start. Distinct streams must use distinct directories.

pub fn name(&self) -> &str

Returns the logical stream name.

pub fn relative_directory(&self) -> &str

Returns the relative directory beneath the recording root.

pub const fn sampling_interval(&self) -> SamplingInterval

Returns the sampling policy.

pub fn fields(&self) -> &[String]

Returns selected state fields in declaration order.

pub const fn storage(&self) -> Option<StateStreamStorage>

Returns stream-specific storage, or None when writer storage applies.
