Struct EpContextPartition 

pub struct EpContextPartition<'a> {
    pub source: &'a str,
    pub ep_sdk_version: &'a str,
    pub partition_name: &'a str,
    pub main_context: bool,
    pub blob: &'a [u8],
    pub covered_nodes: &'a [NodeId],
}

One EP-compiled partition to serialise into an EPContext node (§55.4).

This is the model-agnostic input to the writer: the loader does not depend on onnx-runtime-ep-api, so the session maps its runtime EpContext (+ the EP’s context_source_keys) into this neutral view. Every field is supplied by the caller — no vendor name is baked in.

Fields

source: &'a str

source attribute — the EP’s own dispatch key (§55.6). Never hardcoded.

ep_sdk_version: &'a str

ep_sdk_version attribute — the SDK/toolchain version (from the runtime context’s ep_version). Empty ⇒ the attribute is omitted.

partition_name: &'a str

partition_name attribute — the ORT-partitioned graph name. Empty ⇒ the attribute is omitted.

main_context: bool

main_context attribute — true for a primary node owning the payload.

blob: &'a [u8]

The compiled vendor blob (the runtime context’s data) → the node’s ep_cache_context (inline or sidecar, per embed_mode).

covered_nodes: &'a [NodeId]

The partition’s nodes (the runtime context’s covered_nodes) that this single EPContext node replaces. Their boundary tensors become the node’s variadic i/o.
