1.0.0[−][src]Trait alloc_wg::fmt::Pointer
p
formatting.
The Pointer
trait should format its output as a memory location. This is commonly presented
as hexadecimal.
For more information on formatters, see the module-level documentation.
Examples
Basic usage with &i32
:
let x = &42; let address = format!("{:p}", x); // this produces something like '0x7f06092ac6d0'
Implementing Pointer
on a type:
use std::fmt; struct Length(i32); impl fmt::Pointer for Length { fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result { // use `as` to convert to a `*const T`, which implements Pointer, which we can use let ptr = self as *const Self; fmt::Pointer::fmt(&ptr, f) } } let l = Length(42); println!("l is in memory here: {:p}", l); let l_ptr = format!("{:018p}", l); assert_eq!(l_ptr.len(), 18); assert_eq!(&l_ptr[..2], "0x");
Required methods
fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>
Formats the value using the given formatter.
