Struct SecretString 

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

Opaque wrapper around a secret string value.

Debug and Display both print [REDACTED] — the inner value is never exposed through formatting traits. Use expose for controlled access when constructing HTTP headers or form bodies.

On Drop the backing buffer is securely zeroed via the zeroize crate.

Implementations

impl SecretString

pub fn new(value: impl Into<String>) -> SecretString

Create a new SecretString from a plain value.

pub fn expose(&self) -> &str

Provide read-only access to the underlying secret.

Callers must not log, store, or otherwise persist the returned slice.

Trait Implementations

impl Clone for SecretString

fn clone(&self) -> SecretString

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SecretString

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

Formats the value using the given formatter.

impl Display for SecretString

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

Formats the value using the given formatter.

impl Drop for SecretString

fn drop(&mut self)

Executes the destructor for this type.

impl Zeroize for SecretString

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
