Crate securefmt[][src]

Drop-in replacement for the Debug derive macro that hides fields marked as sensitive.


The following code snippet

struct SensitiveData {
    id: u8,
    secret: u8

fn main() {
    println!("{:?}", SensitiveData { id: 1, secret: 42 })

will print:

SensitiveData { id: 1, secret: <redacted> }

If the ‘debug_mode’ feature is active, the same code will print:

WARN - WARNING: securefmt debug_mode feature is active. Sensitive data may be leaked. It is strongly recommended to disable debug_mode in production releases.
SensitiveData { id: 1, secret: 42 }
