Constant rustc_errors::emitter::MAX_HIGHLIGHT_LINES

pub const MAX_HIGHLIGHT_LINES: usize = 6

🔬 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?

maximum number of lines we will print for each error; arbitrary.
