Struct Config 

pub struct Config {
    pub embeddings: EmbeddingsConfig,
    pub search: SearchConfig,
    pub runtime: RuntimeConfig,
    pub sources: BTreeMap<String, Value>,
    pub storage: BTreeMap<String, String>,
}

Top-level config.toml shape.

Fields

embeddings: EmbeddingsConfig

search: SearchConfig

runtime: RuntimeConfig

sources: BTreeMap<String, Value>

[sources.<adapter>] map: per-adapter config blobs the matching factory deserializes inside its open(). The shape is adapter-defined (filesystem adapters expect { path = "..." }; API-backed adapters expect endpoint + auth keys), so this layer stays opaque. Empty by default; pond sync runs discovery into this map on first use.

storage: BTreeMap<String, String>

[storage] key=value pairs handed verbatim to Lance’s DatasetBuilder::with_storage_options and WriteParams.store_params. Keys are the standard object_store config names (AWS_ACCESS_KEY_ID, AWS_REGION, AWS_ENDPOINT, etc.); see Lance’s DatasetBuilder::with_storage_options doc for the per-scheme variants (S3 / GCS / Azure). pond does not parse or validate these; Lance does. Empty by default; required only when --data-dir is an object-store URI that needs credentials or a non-default region/endpoint. Values here override any matching environment variables.

Implementations

impl Config

pub fn load(path: impl AsRef<Path>) -> Result<Self>

Load config.toml from path if it exists and validate it. A missing file yields the built-in defaults. On success the resolved embedding model id + dim are installed into the process (OnceLock-backed; only the first call per process sticks), so all downstream code paths see a consistent pair without per-handler plumbing.

pub fn resolve_sources( &self, adapter: Option<&str>, ) -> Result<Vec<(String, Value)>>

Resolve the [sources.<adapter>] entries to drive pond sync. With adapter = None returns every entry (the no-arg sync path); with Some(name) returns just that one or errors if it’s not in config. The caller is responsible for the discovery fallback when this returns an empty list. Each tuple’s Value is the opaque config blob to hand to the matching factory’s open().

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Config

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

Formats the value using the given formatter.

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Config

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Config

fn eq(&self, other: &Config) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Config

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
