Struct EpContext 

pub struct EpContext {
    pub ep_name: String,
    pub ep_version: String,
    pub data: Vec<u8>,
    pub covered_nodes: Vec<NodeId>,
    pub device_fingerprint: String,
}

The runtime form of a compiled-EP context (docs/ORT2.md §4 / §55.1).

This is the in-memory representation an EP produces from a freshly compiled subgraph (ExecutionProvider::save_context) or restores at load (ExecutionProvider::load_context), skipping the expensive convert+compile step. It is distinct from the loader’s on-disk EpContextNode/EpContextBlob (which is the serialized, in-graph, tool-portable interchange form); the session maps between the two (§55.3).

Fields

ep_name: String

Name of the EP that produced (and must consume) this context.

ep_version: String

SDK/toolchain version that generated the context (maps to the node’s ep_sdk_version attribute — used for invalidation / diagnostics).

data: Vec<u8>

Opaque compiled vendor blob (maps to the node’s ep_cache_context).

covered_nodes: Vec<NodeId>

Graph nodes this context covers (the partition boundary it replaces).

device_fingerprint: String

Device/target fingerprint the blob was compiled for; filled and validated by the owning EP to reject a mismatched load.

Implementations

impl EpContext

pub fn new( ep_name: impl Into<String>, ep_version: impl Into<String>, data: Vec<u8>, covered_nodes: Vec<NodeId>, device_fingerprint: impl Into<String>, ) -> Self

Construct a runtime context from its parts.
