Struct Error 

pub struct Error {
    pub message: String,
    pub locations: Vec<ErrorLocation>,
    pub path: Vec<String>,
}

The response error type for GraphQL-over-HTTP server responses. As specified in the section 7.1.2 Errors and the Error Result Format subsection of the GraphQL specification.

Fields

message: String

A short, human-readable description of the problem.

From the Error Result Format subsection of the GraphQL specification:

Every error MUST contain an entry with the key message with a string description of the error intended for the developer as a guide to understand and correct the error.

locations: Vec<ErrorLocation>

A list of locations describing the beginning of the associated syntax element causing the error.

From the Error Result Format subsection of the GraphQL specification:

If an error can be associated to a particular point in the requested GraphQL document, it SHOULD contain an entry with the key locations with a list of locations, where each location is a map with the keys line and column, both positive numbers starting from 1 which describe the beginning of an associated syntax element.

path: Vec<String>

A list of path segments starting at the root of the response and ending with the field associated with the error.

From the Error Result Format subsection of the GraphQL specification:

If an error can be associated to a particular field in the GraphQL result, it must contain an entry with the key path that details the path of the response field which experienced the error. This allows clients to identify whether a null result is intentional or caused by a runtime error.

This field should be a list of path segments starting at the root of the response and ending with the field associated with the error. Path segments that represent fields should be strings, and path segments that represent list indices should be 0-indexed integers. If the error happens in an aliased field, the path to the error should use the aliased name, since it represents a path in the response, not in the request.
