Struct rustc_errors::Handler

pub struct Handler {
    pub flags: HandlerFlags,
    // some fields omitted
}

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

A handler deals with errors; certain errors (fatal, bug, unimpl) may cause immediate exit, others log errors for later reporting.
