Struct FeatureEntry 

pub struct FeatureEntry {
    pub id: &'static str,
    pub category: &'static str,
    pub description: &'static str,
    pub batch: FeatureStatus,
    pub streaming: FeatureStatus,
    pub incremental: FeatureStatus,
    pub note: Option<&'static str>,
    pub placement: Option<&'static [Placement]>,
}

A single entry in the Krishiv SQL feature matrix, dimensioned per engine.

Fields

id: &'static str

Stable identifier (e.g. "select.distinct").

category: &'static str

Broad feature category (e.g. "SELECT", "JOIN", "DML").

description: &'static str

Human-readable description.

batch: FeatureStatus

Support status in the batch engine.

streaming: FeatureStatus

Support status in the streaming (continuous) engine.

incremental: FeatureStatus

Support status in the incremental (IVM) engine.

note: Option<&'static str>

Optional clarifying note (gap description, limitations, workarounds).

placement: Option<&'static [Placement]>

Where the feature actually executes. None means the feature is reachable from every surface its engine cells imply (the common case). Some(..) restricts the claim — e.g. embedded-API-only operators — and is rendered into the generated reference page.

Implementations

impl FeatureEntry

pub fn placement_restricted(&self) -> bool

True when the entry’s execution surface is restricted below what its engine cells imply (i.e. it carries an explicit placement set that excludes at least one surface).

pub fn status_for(&self, engine: Engine) -> FeatureStatus

Status for a given engine.
