Extension trait for formatting any error type

This trait is implemented for dyn std::error::Error and uses the error registry to dynamically dispatch to the concrete error type’s apollo_errors::Error implementation.

Example

use apollo_errors::{ErrorExt, FormatConfig};

fn handle_error(error: &dyn std::error::Error) {
    let config = FormatConfig::default();
    let graphql = error.to_graphql(config);
    let json = error.to_json(config);
}

Required Methods

fn to_json(&self, config: FormatConfig) -> Result<Value, Error>

Render this error as JSON format

Errors

Returns an error if any field fails to serialize to JSON

fn to_html(&self, config: FormatConfig) -> String

Render this error as HTML

fn to_graphql(&self, config: FormatConfig) -> Result<Value, Error>

Render this error as GraphQL JSON format

Errors

Returns an error if any field fails to serialize to JSON

fn to_text(&self, config: FormatConfig) -> String

Render this error as plain text

fn to_jsonrpc(&self, config: FormatConfig) -> Result<Value, Error>

Render this error as JSON-RPC 2.0 error format

Errors

Returns an error if any field fails to serialize to JSON

fn http_status(&self) -> StatusCode

Get the HTTP status code for this error

fn http_headers(&self) -> Vec<(HeaderName, HeaderValue)>

Get HTTP headers for this error

Provided Methods

fn to_debug(&self) -> String

where Self: Debug,

Render this error in debug format using Rust’s standard Debug output.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
