Trait std::fmt::Debug 1.0.0[−][src]
? formatting.
Debug should format the output in a programmer-facing, debugging context.
Generally speaking, you should just derive a Debug implementation.
When used with the alternate format specifier #?, the output is pretty-printed.
For more information on formatters, see the module-level documentation.
This trait can be used with #[derive] if all fields implement Debug. When
derived for structs, it will use the name of the struct, then {, then a
comma-separated list of each field's name and Debug value, then }. For
enums, it will use the name of the variant and, if applicable, (, then the
Debug values of the fields, then ).
Examples
Deriving an implementation:
#[derive(Debug)] struct Point { x: i32, y: i32, } let origin = Point { x: 0, y: 0 }; println!("The origin is: {:?}", origin);Run
Manually implementing:
use std::fmt; struct Point { x: i32, y: i32, } impl fmt::Debug for Point { fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result { write!(f, "Point {{ x: {}, y: {} }}", self.x, self.y) } } let origin = Point { x: 0, y: 0 }; println!("The origin is: {:?}", origin);Run
This outputs:
The origin is: Point { x: 0, y: 0 }
There are a number of debug_* methods on Formatter to help you with manual
implementations, such as debug_struct.
Debug implementations using either derive or the debug builder API
on Formatter support pretty printing using the alternate flag: {:#?}.
Pretty printing with #?:
#[derive(Debug)] struct Point { x: i32, y: i32, } let origin = Point { x: 0, y: 0 }; println!("The origin is: {:#?}", origin);Run
This outputs:
The origin is: Point {
x: 0,
y: 0
}
Required Methods
fn fmt(&self, f: &mut Formatter) -> Result<(), Error>
Formats the value using the given formatter.
Examples
use std::fmt; struct Position { longitude: f32, latitude: f32, } impl fmt::Debug for Position { fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result { write!(f, "({:?}, {:?})", self.longitude, self.latitude) } } assert_eq!("(1.987, 2.983)".to_owned(), format!("{:?}", Position { longitude: 1.987, latitude: 2.983, }));Run
