Struct core::fmt::DebugList1.2.0 [] [src]

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

A struct to help with fmt::Debug implementations.

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

This can be constructed by the Formatter::debug_list 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: 'a> DebugList<'a, 'b>

Adds a new entry to the list output.

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

Finishes output and returns any error encountered.
