Enum ProviderConfig 

pub enum ProviderConfig {
    Sidecar(SidecarConfig),
    Onnx(OnnxConfig),
}

Tagged enum over the shipped backends. TOML shape for each backend:

Sidecar (Python HTTP server, zero native deps in mnem):

[sparse]
provider  = "sidecar"
base_url  = "http://localhost:8791"
model     = "opensearch-doc-v3-distill"
vocab_id  = "bert-base-uncased@30522"

Native ONNX (in-process, requires the onnx cargo feature):

[sparse]
provider   = "onnx"
model      = "opensearch-doc-v3-distill"   # or "opensearch-bi-v2-distill"
# max_length = 512                         # optional; default = model ceiling

Variants

Sidecar(SidecarConfig)

HTTP sidecar running the reference Python SPLADE/BGE-M3 implementation. See benchmarks/adapters/splade-sidecar/ in for a Docker image.

Onnx(OnnxConfig)

Native in-process ONNX encoder. Requires building with the onnx feature; otherwise open returns a SparseError::Config explaining the mismatch so operators can either rebuild or switch back to sidecar.

Trait Implementations

impl Clone for ProviderConfig

fn clone(&self) -> ProviderConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProviderConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProviderConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ProviderConfig

fn eq(&self, other: &ProviderConfig) -> 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 ProviderConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ProviderConfig

impl StructuralPartialEq for ProviderConfig
