Struct OasValidatorPlugin 

pub struct OasValidatorPlugin {
    operations: Vec<CompiledOp>,
    rejected_code: u16,
    rejected_msg: Option<String>,
}

Validates requests against a compiled OpenAPI 3 spec.

Fields

operations: Vec<CompiledOp>

rejected_code: u16

rejected_msg: Option<String>

Implementations

impl OasValidatorPlugin

pub fn from_config(config: &HashMap<String, Value>) -> Result<Self, String>

Builds the plugin from node config.

Accepted keys:

• spec (object, required): the OpenAPI 3 document as an inline JSON object. Its paths are walked and every operation’s application/json requestBody schema is compiled and required parameters indexed. A non-object spec, a malformed paths, or an uncompilable schema fails here at config load.
• rejected_code (integer 400–599, default 400): response status for rejected requests.
• rejected_msg (string): fixed message returned instead of the per-violation detail.

                  properties: { name: { type: string } }

fn match_operation(&self, method: &str, path: &str) -> Option<&CompiledOp>

Finds the best-matching operation for a method + path: the matching operation with the most literal (non-templated) segments wins, so an exact path is preferred over a templated one.

fn reject(&self, ctx: Context, detail: String) -> PluginExecutionError

Writes the rejection onto the response and returns the error that routes the context through the node’s error port.

Trait Implementations

impl Plugin for OasValidatorPlugin

fn plugin_type(&self) -> &str

Unique identifier for the plugin type (e.g., “proxy-rewrite”, “upstream”).

fn execute<'life0, 'life1, 'async_trait>( &'life0 self, ctx: Context, _named_inputs: &'life1 HashMap<String, Value>, ) -> Pin<Box<dyn Future<Output = Result<PluginOutput, PluginExecutionError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Executes the plugin logic against the request/response context.
