Struct NameComponent 

pub struct NameComponent {
    pub typ: u64,
    pub value: Bytes,
}

A single NDN name component: a (type, value) pair.

The value is a zero-copy slice of the original packet buffer.

Ordering follows the NDN Packet Format v0.3 §2.1 canonical order: TLV-TYPE first, then TLV-LENGTH (shorter is smaller), then TLV-VALUE byte-by-byte. This matches the order used by NFD and ndn-cxx.

Fields

typ: u64

value: Bytes

Implementations

impl NameComponent

pub fn new(typ: u64, value: Bytes) -> NameComponent

pub fn generic(value: Bytes) -> NameComponent

pub fn blake3_digest(hash: [u8; 32]) -> NameComponent

Create a BLAKE3 content-digest component (type 0x03, 32 bytes).

Experimental / NDA extension. The 32-byte BLAKE3 hash of a block’s content forms a self-certifying name component in NDA zones. The actual BLAKE3 computation must be performed by the caller.

pub fn as_blake3_digest(&self) -> Option<[u8; 32]>

Extract the 32-byte BLAKE3 digest value, or None if this is not a BLAKE3_DIGEST (type 0x03) component or the value is not 32 bytes.

pub fn keyword(value: Bytes) -> NameComponent

Create a Keyword component (type 0x20) with opaque bytes.

pub fn byte_offset(offset: u64) -> NameComponent

Create a ByteOffset component (type 0x34), big-endian with leading zeros stripped.

pub fn version(v: u64) -> NameComponent

Create a Version component (type 0x36), big-endian with leading zeros stripped.

pub fn timestamp(ts: u64) -> NameComponent

Create a Timestamp component (type 0x38), big-endian with leading zeros stripped.

pub fn sequence_num(seq: u64) -> NameComponent

Create a SequenceNum component (type 0x3A), big-endian with leading zeros stripped.

pub fn as_segment(&self) -> Option<u64>

Decode a Segment component value as u64. Returns None if not type 0x32.

pub fn as_byte_offset(&self) -> Option<u64>

Decode a ByteOffset component value as u64. Returns None if not type 0x34.

pub fn as_version(&self) -> Option<u64>

Decode a Version component value as u64. Returns None if not type 0x36.

pub fn as_timestamp(&self) -> Option<u64>

Decode a Timestamp component value as u64. Returns None if not type 0x38.

pub fn as_sequence_num(&self) -> Option<u64>

Decode a SequenceNum component value as u64. Returns None if not type 0x3A.

Trait Implementations

impl Clone for NameComponent

fn clone(&self) -> NameComponent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NameComponent

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

Formats the value using the given formatter.

impl Hash for NameComponent

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

where __H: Hasher,

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 NameComponent

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

NDN canonical component ordering (NDN Packet Format v0.3 §2.1).

Order: TLV-TYPE ascending, then TLV-LENGTH ascending (shorter is smaller), then TLV-VALUE byte-by-byte ascending.

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 NameComponent

fn eq(&self, other: &NameComponent) -> 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 NameComponent

fn partial_cmp(&self, other: &NameComponent) -> 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.
