1.0.0[−][src]Trait conshomfold::Display
Format trait for an empty format, {}
.
Display
is similar to Debug
, but Display
is for user-facing
output, and so cannot be derived.
For more information on formatters, see the module-level documentation.
Examples
Implementing Display
on a type:
use std::fmt; struct Point { x: i32, y: i32, } impl fmt::Display for Point { fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result { write!(f, "({}, {})", self.x, self.y) } } let origin = Point { x: 0, y: 0 }; assert_eq!(format!("The origin is: {}", origin), "The origin is: (0, 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::Display for Position { fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result { write!(f, "({}, {})", self.longitude, self.latitude) } } assert_eq!("(1.987, 2.983)", format!("{}", Position { longitude: 1.987, latitude: 2.983, }));

impl Display for Hir
Print a display representation of this Hir.
The result of this is a valid regular expression pattern string.
This implementation uses constant stack space and heap space proportional
to the size of the Hir
.
impl Display for Error
impl Display for Error
impl Display for Ast
Print a display representation of this Ast.
This does not preserve any of the original whitespace formatting that may have originally been present in the concrete syntax from which this Ast was generated.
This implementation uses constant stack space and heap space proportional
to the size of the Ast
.
