Struct std::fmt::DebugTuple 1.2.0
[−]
[src]
#[must_use]pub struct DebugTuple<'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 tuple as a part of your
Debug::fmt
implementation.
This can be constructed by the
Formatter::debug_tuple
method.
Examples
use std::fmt; struct Foo(i32, String); impl fmt::Debug for Foo { fn fmt(&self, fmt: &mut fmt::Formatter) -> fmt::Result { fmt.debug_tuple("Foo") .field(&self.0) .field(&self.1) .finish() } } // prints "Foo(10, "Hello World")" println!("{:?}", Foo(10, "Hello World".to_string()));Run
