Struct CatalogConfig 

pub struct CatalogConfig {
    pub default: HashMap<String, String>,
    pub named: HashMap<String, HashMap<String, String>>,
}

Catalog configuration loaded from dnx.toml [catalog]/[catalogs.*] sections, or falling back to dnx.catalog.toml.

Allows centralised version management across workspace members. Members reference versions via "catalog:" (default group) or "catalog:<group>" (named group).

Fields

default: HashMap<String, String>

Default catalog entries: package name → version range.

named: HashMap<String, HashMap<String, String>>

Named catalog groups: group name → { package name → version range }.

Implementations

impl CatalogConfig

pub fn load(root: &Path) -> Result<Option<Self>>

Load catalog config, checking multiple sources in order:

1. dnx.toml [catalog] and [catalogs.*] sections (via DnxConfig)
2. dnx.catalog.toml (legacy)

Returns Ok(None) if no catalog configuration is found.

pub fn load_from_catalog_toml(root: &Path) -> Result<Option<Self>>

Load catalog config from dnx.catalog.toml only (legacy support). Returns Ok(None) if the file does not exist.

pub fn from_maps( default: HashMap<String, String>, named: HashMap<String, HashMap<String, String>>, ) -> Self

Create a CatalogConfig directly from default and named maps.

pub fn resolve(&self, pkg_name: &str, spec: &str) -> Result<String>

Resolve a catalog: specifier for the given package name.

• "catalog:" → look up pkg_name in default
• "catalog:testing" → look up pkg_name in named.testing
