Crate oxidelake_api 

Public API facade (docs/SPEC.md §2.8): the fluent DataFrame API and SQL entry points over the runtime — OxideSession for sessions (embedded or cluster), OxideFrame for queries, and the l2_distance / cosine_distance SQL UDFs registered on every session.

use oxidelake_api::prelude::*;

let session = OxideSession::local()?;
session.register_parquet("t", "data/").await?;
let top = session
    .table("t")
    .await?
    .filter(col("k").gt_eq(lit(2)))?
    .vector_distance("emb", &[0.0; 8], DistanceMetric::L2, "d")?
    .sort(vec![col("d").sort(true, false)])?
    .limit(10)?
    .collect()
    .await?;

Dependency direction: depends on oxidelake-runtime (and oxidelake-core).

Modules

Enums

BackendKind

The execution backends OxideLake knows about.

DistanceMetric

Distance metric for the vector kernel.

EngineError

Errors produced by OxideLake library crates.

SessionMode

Where a session executes.

Traits

OxideSessionExt
