Struct ParseErrorInfo 

pub struct ParseErrorInfo {
    pub duplicated_field: Option<String>,
}

Out-of-band data an error carries for the server’s own use.

Nothing here is ever serialized into a response body. Upstream’s equivalent is err.userInfo, which the error middleware never renders: it writes code and message and nothing else (middlewares.js:617).

The point of the type is that the alternative is worse. Recovering which unique index collided by leaving the driver’s text in message and parsing it downstream puts the database name and the colliding value on the wire, which is the disclosure this replaces.

Fields

duplicated_field: Option<String>

err.userInfo.duplicated_field (MongoStorageAdapter.js:584). The field whose unique index a write collided on.
