Struct std::fmt::DebugSet1.2.0 [] [src]

pub struct DebugSet<'a, 'b> where
    'b: 'a, 
{ /* fields omitted */ }

A struct to help with fmt::Debug implementations.

This is useful when you wish to output a formatted set of items as a part of your Debug::fmt implementation.

This can be constructed by the Formatter::debug_set method.


use std::fmt;

struct Foo(Vec<i32>);

impl fmt::Debug for Foo {
    fn fmt(&self, fmt: &mut fmt::Formatter) -> fmt::Result {

// prints "{10, 11}"
println!("{:?}", Foo(vec![10, 11]));Run


impl<'a, 'b> DebugSet<'a, 'b> where
    'b: 'a, 

Adds a new entry to the set output.

Adds the contents of an iterator of entries to the set output.

Finishes output and returns any error encountered.
