Struct DomainTag 

pub struct DomainTag { /* private fields */ }

Validated domain-separation tag appended to derived-key info.

A tag may identify a tenant, account, or protocol scope. It is therefore redacted in diagnostics and clears its owned bytes on drop.

Implementations

impl DomainTag

pub fn from_slice(input: &[u8]) -> Result<DomainTag, CryptoError>

Build a domain tag, requiring 1..=48 bytes drawn only from lowercase ASCII letters, digits, and /, _, or -; otherwise returns an error.

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

Borrow the domain tag bytes.

Trait Implementations

impl Debug for DomainTag

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

Formats the value using the given formatter.

impl Drop for DomainTag

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 DomainTag

impl PartialEq for DomainTag

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for DomainTag

impl Zeroize for DomainTag

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.
