Struct LvsModel 

pub struct LvsModel {
    pub version: u64,
    pub start_id: u64,
    pub named_pattern_cnt: u64,
    pub nodes: Vec<LvsNode>,
    pub tag_symbols: Vec<LvsTagSymbol>,
    /* private fields */
}

A parsed LVS trust schema.

See the module docs for which LVS features are supported. Construct via LvsModel::decode (typically via crate::TrustSchema::from_lvs_binary).

Fields

version: u64

start_id: u64

named_pattern_cnt: u64

nodes: Vec<LvsNode>

tag_symbols: Vec<LvsTagSymbol>

Implementations

impl LvsModel

pub fn decode(input: &[u8]) -> Result<Self, LvsError>

Parse an LVS binary model from its TLV wire bytes.

The top-level LvsModel has no outer TLV wrapper — the input buffer is a sequence of top-level TLV fields (Version, StartId, NamedPatternCnt, *Node, *TagSymbol).

pub fn uses_user_functions(&self) -> bool

Returns true if the loaded schema references any user functions.

Because v0.1.0 does not dispatch user functions, any rule that depends on one will never match a packet. Callers that need bit-exact parity with python-ndn’s evaluation can inspect this flag and refuse to use the schema.

pub fn check(&self, data_name: &Name, key_name: &Name) -> bool

Check whether data_name is allowed to be signed by key_name under this LVS schema. Returns true if:

1. data_name reaches some node D in the graph, and
2. D has at least one SignConstraint, and
3. key_name reaches a node whose id is listed in D.sign_constraints.

Trait Implementations

impl Clone for LvsModel

fn clone(&self) -> LvsModel

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

Performs copy-assignment from source.

impl Debug for LvsModel

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