Struct Token 

pub struct Token { /* private fields */ }

Represents a token generated by Totp. This can be thought of as a string with a few notable difference:

• It is only stack allocated
• Comparison is done in constant time regardless of the number of digits in the token
• Formatting is lazily evaluated

Since it implements Display, it can be directly used in formatting just like a string:

let text: String = format!("{}", token);

While Token implements Eq, it’s strongly recommended that you rely on check instead, as that will take skew into account.

Note that while Token is stack-allocated and only contains plain data, it does not implement Copy. This is to preserve compatibility with the zeroize feature which will add a non-trivial Drop implementation.

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Token

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

Formats the value using the given formatter.

impl Display for Token

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

Formats the value using the given formatter.

impl Drop for Token

Available on crate feature zeroize only.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Eq for Token

impl PartialEq for Token

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

Equality operator ==.

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

Inequality operator !=.

impl Zeroize for Token

Available on crate feature zeroize only.

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.
