León Orell Valerian Liehr ae88766286 Rollup merge of #123703 - estebank:diag-changes-2, r=Nadrieril ... Use `fn` ptr signature instead of `{closure@..}` in infer error When suggesting a type on inference error, do not use `{closure@..}`. Instead, replace with an appropriate `fn` ptr. On the error message, use `short_ty_string` and write long types to disk. ``` error[E0284]: type annotations needed for `Select<{closure@lib.rs:2782:13}, _, Expression<'_>, _>` --> crates/lang/src/parser.rs:41:13 | 41 | let lit = select! { | ^^^ 42 | Token::Int(i) = e => Expression::new(Expr::Lit(ast::Lit::Int(i.parse().unwrap())), e.span()), | ---- type must be known at this point | = note: the full type name has been written to '/home/gh-estebank/iowo/target/debug/deps/lang-e2d6e25819442273.long-type-4587393693885174369.txt' = note: cannot satisfy `<_ as chumsky::input::Input<'_>>::Span == SimpleSpan` help: consider giving `lit` an explicit type, where the type for type parameter `I` is specified | 41 | let lit: Select<for<'a, 'b> fn(tokens::Token<'_>, &'a mut MapExtra<'_, 'b, _, _>) -> Option<Expression<'_>>, _, Expression<'_>, _> = select! { | +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ``` instead of ``` error[E0284]: type annotations needed for `Select<{closure@/home/gh-estebank/.cargo/registry/src/index.crates.io-6f17d22bba15001f/chumsky-1.0.0-alpha.6/src/lib.rs:2782:13: 2782:28}, _, Expression<'_>, _>` --> crates/lang/src/parser.rs:41:13 | 41 | let lit = select! { | ^^^ 42 | Token::Int(i) = e => Expression::new(Expr::Lit(ast::Lit::Int(i.parse().unwrap())), e.span()), | ---- type must be known at this point | = note: cannot satisfy `<_ as chumsky::input::Input<'_>>::Span == SimpleSpan` help: consider giving `lit` an explicit type, where the type for type parameter `I` is specified | 41 | let lit: Select<{closure@/home/gh-estebank/.cargo/registry/src/index.crates.io-6f17d22bba15001f/chumsky-1.0.0-alpha.6/src/lib.rs:2782:13: 2782:28}, _, Expression<'_>, _> = select! { | ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ``` Address #123630 (test missing).		2024-04-11 01:56:26 +02:00
