Struct TlvSection 

pub struct TlvSection {
    pub use_site_path_overrides: Option<Vec<(u8, UseSitePath)>>,
    pub fingerprints: Option<Vec<(u8, [u8; 4])>>,
    pub pubkeys: Option<Vec<(u8, [u8; 65])>>,
    pub origin_path_overrides: Option<Vec<(u8, OriginPath)>>,
    pub unknown: Vec<(u8, Vec<u8>, usize)>,
}

Decoded TLV section. Fields are populated from per-tag readers; unknown tags are preserved verbatim per D6 forward-compat.

Fields

use_site_path_overrides: Option<Vec<(u8, UseSitePath)>>

Per-@N use-site path overrides, if present.

fingerprints: Option<Vec<(u8, [u8; 4])>>

Per-@N xpub fingerprints (4 bytes each), if present.

pubkeys: Option<Vec<(u8, [u8; 65])>>

Per-@N xpub bytes (32-byte chain code || 33-byte compressed pubkey), if present. Wallet-policy mode predicate is pubkeys.is_some() && !pubkeys.unwrap().is_empty().

origin_path_overrides: Option<Vec<(u8, OriginPath)>>

Per-@N origin-path overrides for wrappers whose canonical path is either undefined or has been overridden, if present.

unknown: Vec<(u8, Vec<u8>, usize)>

Raw payload of unknown TLVs, keyed by tag, for forward-compat round-trip. Decoders preserve unknown TLVs verbatim through re-encoding.

Implementations

impl TlvSection

pub fn new_empty() -> Self

Create an empty TLV section (no entries).

pub fn is_empty(&self) -> bool

Returns true if no TLV entries are present.

pub fn write(&self, w: &mut BitWriter, key_index_width: u8) -> Result<(), Error>

Encode this TLV section onto w. Entries are emitted in ascending tag order. key_index_width is the bit-width of the per-@N placeholder index field.

Errors

• Error::EmptyTlvEntry if any of use_site_path_overrides, fingerprints, pubkeys, or origin_path_overrides is Some(vec![]). Empty TLVs violate the §7.5 omission discipline and are rejected at the encoder boundary.
• Error::OverrideOrderViolation if any entry vector is not strictly ascending in idx.
• Encoding errors from contained values (OriginPath::write, etc.).

pub fn read( r: &mut BitReader<'_>, key_index_width: u8, n: u8, ) -> Result<Self, Error>

Decode a TLV section from r, consuming all remaining bits. key_index_width is the bit-width of placeholder indices; n is the key count.

Trait Implementations

impl Clone for TlvSection

fn clone(&self) -> TlvSection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TlvSection

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

Formats the value using the given formatter.

impl PartialEq for TlvSection

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