Struct ErrorHandlerPlugin 

pub struct ErrorHandlerPlugin {
    status_code: u16,
    body_template: String,
}

Overwrites Context.response with a configured status code and a body rendered from a template. The template may reference the most recent entry in Context.errors via {{error.code}}, {{error.message}}, and {{error.node_id}} placeholders; the content type is forced to application/json.

Fields

status_code: u16

body_template: String

Implementations

impl ErrorHandlerPlugin

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

Builds the plugin from node config.

Accepted keys (all optional; this constructor never errors):

• status_code (integer, default 500): HTTP status of the error response.
• body_template (string, default a generic {"error": "internal_error", ...} JSON body): response body, with {{error.code}}, {{error.message}}, and {{error.node_id}} substituted from the last error in the context at execution time.

type: error-handler
config:
  status_code: 502
  body_template: '{"error": "{{error.code}}", "message": "{{error.message}}"}'

Trait Implementations

impl Plugin for ErrorHandlerPlugin

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.
