Struct Secret 

pub struct Secret(/* private fields */);

Wrapper for secrets that redacts values in logs/debug output

Prevents accidental secret exposure through string formatting

Example

let secret = Secret::new("password123".to_string());
println!("{:?}", secret);  // Prints: Secret(***)
let actual = secret.expose();  // Returns: "password123"

Implementations

impl Secret

pub fn new(value: String) -> Self

Create new Secret wrapper

pub fn expose(&self) -> &str

Expose the actual secret value

Should only be called when actually using the secret Not called in logging or debugging code

pub fn into_exposed(self) -> String

Convert to owned String (consumes Secret)

pub fn is_empty(&self) -> bool

Check if secret is empty

pub fn len(&self) -> usize

Get length of secret

Trait Implementations

impl Clone for Secret

fn clone(&self) -> Secret

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Secret

Debug output redacts actual secret value

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Secret

Display output redacts actual secret value

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Secret

Partial equality that compares actual values (for testing)

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
