Struct NSec3

pub struct NSec3 {
    pub name: Name,
    pub hash_algo: u8,
    pub flags: u8,
    pub hash_iterations: u16,
    pub salt: Vec<u8>,
    pub next_name_hash: Vec<u8>,
    pub types: NSecTypeMask,
}

A Next Secure Record resource record. This indicates a range of possible names for which there is no such record.

Fields

name: Name

The name this record is at.

hash_algo: u8

The hash algorithm used to hash the name and Self::next_name_hash. Currently only 1 (SHA-1) is defined.

flags: u8

Flags for this record. Currently only bit 0 (the “opt-out” bit) is defined.

hash_iterations: u16

The number of hash iterations required.

As of RFC 9276 this MUST be set to 0, but sadly is often still set higher in the wild. A hard cap is applied in validation.

salt: Vec<u8>

The salt included in the hash.

As of RFC 9276 this SHOULD be empty, but often isn’t in the wild.

next_name_hash: Vec<u8>

The hash of the next name which contains a record. There are no records who’s name’s hash lies between name and Self::next_name_hash.

types: NSecTypeMask

The set of record types which exist at name. Any other record types do not exist at name.

Trait Implementations

impl Clone for NSec3

fn clone(&self) -> NSec3

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NSec3

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

Formats the value using the given formatter.

impl From<NSec3> for RR

fn from(nsec3: NSec3) -> RR

Converts to this type from the input type.

impl Hash for NSec3

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NSec3

fn cmp(&self, other: &NSec3) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NSec3

fn eq(&self, other: &NSec3) -> 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.

impl PartialOrd for NSec3

fn partial_cmp(&self, other: &NSec3) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
