Struct TokenHash 

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

The SHA-256 of a token: what the app stores and looks tokens up by.

Implementations

impl TokenHash

pub fn of(token: &str) -> Option<Self>

The hash of a presented token, or None when it is not a well-formed token. Leading and trailing whitespace is ignored.

pub const fn from_bytes(bytes: [u8; 32]) -> Self

Rebuilds a hash read back from storage.

pub const fn as_bytes(&self) -> &[u8; 32]

The 32 bytes to store.

pub fn verify(&self, token: &str) -> bool

Whether token hashes to this value, compared in constant time.
