Struct TagRegistry 

pub struct TagRegistry { /* private fields */ }

A set of custom YAML tags that the streaming deserializer should strip and pass through instead of routing via the AST fallback.

Clone-cheap (just a set of owned strings); typically wrapped in an Arc and shared across calls. See the module-level documentation for semantics.

Examples

use noyalib::TagRegistry;
let mut reg = TagRegistry::new();
let _ = reg.register("!Celsius");
let _ = reg.register("!Meters");
assert!(reg.contains("!Celsius"));
assert_eq!(reg.len(), 2);

Implementations

impl TagRegistry

pub fn new() -> Self

Construct an empty registry.

Examples

let reg = noyalib::TagRegistry::new();
assert!(reg.is_empty());

pub fn register(&mut self, tag: impl Into<String>) -> &mut Self

Mark tag as known. Accepts both handle-prefixed forms (!Celsius, !!custom) and verbatim tag text. Returns &mut self so callers can chain registrations.

Examples

let mut reg = noyalib::TagRegistry::new();
let _ = reg.register("!Celsius").register("!Fahrenheit");
assert!(reg.contains("!Celsius"));
assert!(reg.contains("!Fahrenheit"));

pub fn with(self, tag: impl Into<String>) -> Self

Chainable register that consumes self — convenient when building a registry inline.

Examples

let reg = noyalib::TagRegistry::new()
    .with("!Celsius")
    .with("!Meters");
assert_eq!(reg.len(), 2);

pub fn contains(&self, tag: &str) -> bool

Is tag registered as a strip-through tag?

Examples

let reg = noyalib::TagRegistry::new().with("!Celsius");
assert!(reg.contains("!Celsius"));
assert!(!reg.contains("!Fahrenheit"));

pub fn len(&self) -> usize

Number of tags registered.

Examples

let reg = noyalib::TagRegistry::new().with("!A").with("!B");
assert_eq!(reg.len(), 2);

pub fn is_empty(&self) -> bool

Returns true when no tags are registered.

Examples

assert!(noyalib::TagRegistry::new().is_empty());

pub fn clear(&mut self)

Remove every registration.

Examples

let mut reg = noyalib::TagRegistry::new().with("!A");
reg.clear();
assert!(reg.is_empty());
