Crate error_path 

error-path adds stable, structured operational addresses to Rust errors.

The crate is intentionally tiny:

• WithErrorPath is the compatibility trait used by macros.
• ErrorPath is a structured operational address.
• Optional features adapt anyhow, eyre, error-stack, and stacked_errors.

Example

use error_path::ErrorPath;

let mut error_path = ErrorPath::from_segment("http.0405");
error_path.prepend_path("login.api.request_login");

assert_eq!(error_path.to_string(), "login.api.request_login.http.0405");

Structs

ErrorPath

A structured operational error address.

Enums

SetPathDelimiterError

Error returned when the process-wide path delimiter cannot be configured.

Traits

ErrorPathExt

Read a structured operational address from an error.

WithErrorPath

Compatibility trait used by the generated macro code.

Functions

path_delimiter

Return the process-wide path delimiter.

set_path_delimiter

Set the process-wide delimiter used by ErrorPath Display.
