Struct Asn

pub struct Asn { /* private fields */ }

ASN – Autonomous System Number

Implementations

impl Asn

pub const RESERVED: Self

pub const TRANSITION: Self

pub const fn new_16bit(asn: u16) -> Self

Constructs a new 2-octet Asn.

pub const fn new_32bit(asn: u32) -> Self

Constructs a new 4-octet Asn.

pub const fn required_len(&self) -> AsnLength

Gets the size required to store this ASN

pub const fn is_private(&self) -> bool

Checks if the given ASN is reserved for private use.

https://datatracker.ietf.org/doc/rfc7249/

pub const fn is_reserved(&self) -> bool

Checks if the given ASN is reserved. This is done by checking if the asn is included within IANA’s “Special-Purpose AS Numbers” registry. This includes checking against private ASN ranges, ASNs reserved for documentation, and ASNs reserved for specific uses by various RFCs.

Up to date as of 2023-03-01 (Registry was last updated 2015-08-07).

For additional details see:

• https://datatracker.ietf.org/doc/rfc7249/
• https://www.iana.org/assignments/iana-as-numbers-special-registry/iana-as-numbers-special-registry.xhtml

pub const fn is_reserved_for_documentation(&self) -> bool

Checks if the given ASN is reserved for use in documentation and sample code.

https://datatracker.ietf.org/doc/rfc7249/

pub const fn is_four_byte(&self) -> bool

Return if an ASN is 4 bytes or not.

pub const fn to_u32(&self) -> u32

Return AS number as u32.

pub fn encode(&self) -> Bytes

Trait Implementations

impl Clone for Asn

fn clone(&self) -> Asn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Asn

impl FromStr for Asn

Parse an ASN matching the pattern (AS)?[0-9]+.

type Err = <u32 as FromStr>::Err

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Asn

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 Asn

fn cmp(&self, other: &Self) -> 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<i32> for Asn

fn eq(&self, other: &i32) -> 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 PartialEq<u16> for Asn

fn eq(&self, other: &u16) -> 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 PartialEq<u32> for Asn

fn eq(&self, other: &u32) -> 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.
