Struct ErrorChain 

pub struct ErrorChain<'a>(pub &'a (dyn Error + 'static));

Renders an error followed by every cause in its source chain, outer: cause: root.

An error type’s own message names what failed and leaves the cause to std::error::Error::source; this is where a reader that wants the whole story (an MCP client, a log line) joins them once. No cause is skipped, so a type must not also print its source in its own message.

Examples

use std::path::PathBuf;

use mcpls_core::error::{Error, ErrorChain};

let error = Error::FileIo {
    path: PathBuf::from("a.rs"),
    source: std::io::Error::new(std::io::ErrorKind::NotFound, "gone"),
};

assert_eq!(ErrorChain(&error).to_string(), "file I/O error for \"a.rs\": gone");
