This is not used for highlighting or rendering any error message. Rather, it can be used as a sort key to sort a buffer of diagnostics. By default, it is the primary span of span if there is one. Otherwise, it is DUMMY_SP.

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Adds a span/label to be included in the resulting snippet. This label will be shown together with the original span/label used when creating the diagnostic, not a span added by one of the span_* methods.

This is pushed onto the MultiSpan that was created when the diagnostic was first built. If you don't call this function at all, and you just supplied a Span to create the diagnostic, then the snippet will just include that Span, which is called the primary span.

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Prints out a message with a suggested edit of the code.

In case of short messages and a simple suggestion, rustc displays it as a label:

try adding parentheses: `(tup.0).1`

The message

  • should not end in any punctuation (a : is added automatically)
  • should not be a question (avoid language like "did you mean")
  • should not contain any phrases like "the following", "as shown", etc.
  • may look like "to do xyz, use" or "to do xyz, use abc"
  • may contain a name of a function, variable, or type, but not whole expressions
