Struct PypiIndexConfig 

pub struct PypiIndexConfig { /* private fields */ }

Resolved index configuration for one requirements.txt/pyproject.toml file.

Built once per parse (two-pass for requirements.txt — see parser::requirements’s module doc; single-pass for pyproject.toml, whose TOML tree is fully available before any dependency is resolved), consulted per-dependency via Self::resolve_source_for.

Implementations

impl PypiIndexConfig

pub fn new() -> Self

An empty config — every dependency resolves to plain DependencySource::Registry, byte-identical to today (US-004).

pub fn set_primary(&mut self, raw: &str, policy: &RegistryAccessPolicy)

FR-002: sets (overwriting any prior value) the explicit --index-url/Poetry primary-equivalent primary. Matches pip’s own argparse store semantics for --index-url (not append, unlike --extra-index-url) — the last occurrence in a file wins.

pub fn add_extra(&mut self, raw: &str, policy: &RegistryAccessPolicy)

FR-003: appends an --extra-index-url/Poetry supplemental-priority/uv non-default entry to the fallback chain, in declaration order.

pub fn resolve_source_for(&self, named_source: Option<&str>) -> DependencySource

FR-002/FR-003/FR-005/FR-006/FR-007/FR-013: resolves one dependency’s DependencySource.

named_source is Some("internal") for a dependency declaring source = "internal" (Poetry) or an index = "internal" uv-sources binding; None for every other dependency (routes through primary/extras/tail_hop per FR-005 instead).

• A named-source reference resolves to that source’s own URL, or DependencySource::CustomRegistry if the name is unresolved or the source is invalid (fail-closed, never a silent pypi.org fallback — FR-006).
• No override anywhere (no primary, no case-(b) declaration) -> plain DependencySource::Registry (US-004).
• An explicit primary present but invalid -> DependencySource::CustomRegistry (fail-closed — never falls through to the extras chain, matching an explicit --index-url’s replace, not add, semantics).
• Otherwise -> DependencySource::AlternateRegistry pointing at the chain ResolvedChain::key this same config’s Self::resolved_chains registers.

pub fn resolved_chains(&self) -> Vec<ResolvedChain>

Every chain this config implies, ready for registration — FR-005(a)/(b) resolved to concrete hop lists, plus one single-hop chain per valid named source. Empty when the file declares nothing (US-004) or when every case-(b) hop turned out invalid with no explicit primary (N5’s zero-hop case — Self::resolve_source_for returns plain Registry in that case, and there is nothing to register).
