Implementations

fn print_call_post(&mut self, args: &[P<Expr>])

Prints an expr using syntax that’s acceptable in a condition position, such as the cond in if cond { ... }.

Prints expr or (expr) when needs_par holds.

Pretty-prints an item.

Print a let pat = expr expression.

Trait Implementations

The resulting type after dereferencing.

Dereferences the value.

Mutably dereferences the value.

This doesn’t deserve to be called “pretty” printing, but it should be meaning-preserving. A quick hack that might help would be to look at the spans embedded in the TTs to decide where to put spaces and newlines. But it’d be better to parse these according to the grammar of the appropriate macro, transcribe back into the grammar we just parsed from, and then pretty-print the resulting AST nodes (so, e.g., we print expression arguments as expressions). It can be done! I think. Read more

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
