Struct NamePattern 

pub struct NamePattern(pub Vec<PatternComponent>);

A name pattern with named capture groups.

Used by the trust schema to express rules like: “Data under /sensor/<node>/<type> must be signed by /sensor/<node>/KEY/<id>” where <node> must match in both patterns.

Text format

Patterns can be parsed from and serialized to a human-readable string:

• /literal → PatternComponent::Literal
• /<var> → PatternComponent::Capture — matches one name component
• /<**var> → PatternComponent::MultiCapture — matches all remaining components (must be last)

Example: /sensor/<node>/KEY/<id> parses to [Literal("sensor"), Capture("node"), Literal("KEY"), Capture("id")].

Tuple Fields

0: Vec<PatternComponent>

Implementations

impl NamePattern

pub fn parse(s: &str) -> Result<Self, PatternParseError>

Parse a pattern from a text string.

Components are /-separated. An empty leading / is ignored. <var> is a single-component capture; <**var> is a multi-component capture (must be the last component in the pattern).

Examples

use ndn_security::trust_schema::NamePattern;

let p = NamePattern::parse("/sensor/<node>/KEY/<id>").unwrap();

pub fn matches( &self, name: &Name, bindings: &mut HashMap<Arc<str>, NameComponent>, ) -> bool

Attempt to match name against this pattern, extending bindings. Returns true if the match succeeds.

Trait Implementations

impl Clone for NamePattern

fn clone(&self) -> NamePattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NamePattern

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

Formats the value using the given formatter.

impl Display for NamePattern

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

Serialize a pattern to its text form, e.g. /sensor/<node>/KEY/<id>.

impl PartialEq for NamePattern

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