Struct EpContextNode 

pub struct EpContextNode<'g> {
    pub node: NodeId,
    pub source: Option<&'g str>,
    pub main_context: bool,
    pub embed_mode: EmbedMode,
    pub sdk_version: Option<&'g str>,
    pub partition_name: Option<&'g str>,
    /* private fields */
}

A typed view over a com.microsoft::EPContext node in the Graph IR (§55.3). Backed by an ordinary Node plus its attributes — no separate IR node kind. Constructed via EpContextNode::from_node or enumerated with ep_context_nodes.

Variadic boundary tensors are read straight from the underlying node via inputs / outputs; no fixed arity is assumed.

Fields

node: NodeId

The id of the backing IR node.

source: Option<&'g str>

source attribute — the EP dispatch key (§55.6). None if absent.

main_context: bool

main_context != 0 (§55.2 default true when the attribute is absent).

embed_mode: EmbedMode

Embedded vs. external payload (§55.2 default EmbedMode::Embedded).

sdk_version: Option<&'g str>

ep_sdk_version attribute — SDK/toolchain version (diagnostics).

partition_name: Option<&'g str>

partition_name attribute — the ORT-partitioned graph name.

Implementations

impl<'g> EpContextNode<'g>

pub fn from_node(node: &'g Node) -> Option<Self>

Build the typed view if node is a com.microsoft::EPContext node, otherwise None. Attribute parsing is defensive: missing or wrong-typed attributes fall back to the §55.2 defaults rather than erroring.

pub fn inputs(&self) -> &'g [Option<ValueId>]

The node’s variadic input value slots (partition boundary inputs, in order). None slots preserve positional arity for skipped optionals.

pub fn outputs(&self) -> &'g [ValueId]

The node’s variadic output values (partition boundary outputs, in order).

pub fn inner(&self) -> &'g Node

The backing Node.

Trait Implementations

impl<'g> Debug for EpContextNode<'g>

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

Formats the value using the given formatter.
