Struct CatalogRegistry 

pub struct CatalogRegistry { /* private fields */ }

A collection of argumentation schemes, indexed for lookup.

Implementations

impl CatalogRegistry

pub fn new() -> Self

Create an empty registry.

pub fn register(&mut self, scheme: SchemeSpec)

Register a scheme. The last write wins for duplicate ids or keys — the crate::catalog tests guarantee no duplicates exist in the default catalog.

pub fn by_id(&self, id: SchemeId) -> Option<&SchemeSpec>

Look up a scheme by its unique id.

pub fn by_key(&self, key: &str) -> Option<&SchemeSpec>

Look up a scheme by its snake_case key (derived from the name).

pub fn by_category(&self, category: SchemeCategory) -> Vec<&SchemeSpec>

Return all schemes in a given category.

pub fn all(&self) -> &[SchemeSpec]

Return all registered schemes.

pub fn len(&self) -> usize

Number of registered schemes.

pub fn is_empty(&self) -> bool

Whether the registry is empty.

pub fn with_walton_catalog() -> Self

Build a registry preloaded with the canonical Walton (2008) argumentation-scheme catalog.

Distinct from Default::default(), which returns an empty registry. Reach for this when you want the full scheme library; reach for Default::default() or new() when you want an empty registry to populate yourself.

pub fn by_name(&self, name: &str) -> Option<&SchemeSpec>

Look up a scheme by its canonical (human-readable) name.

Names are matched exactly (case-sensitive). Use Self::by_key to look up by the derived snake_case key instead.

Trait Implementations

impl Default for CatalogRegistry

fn default() -> Self

Returns the “default value” for a type.
