Enum SourceReplacement 

pub enum SourceReplacement {
    None,
    SparseMirror {
        index: RegistryIndex,
        auth: Option<AuthToken>,
    },
}

Where a [source.crates-io] replace-with chain resolved to, for plain (Registry-sourced) dependencies (spec FR-005/FR-006/FR-007).

Variants

None

No [source] override applies — no [source.crates-io] table, a directory/ local-registry/non-sparse-git terminal (FR-006), a cyclic/unbounded chain (FR-007), or a terminal that failed RegistryIndex::new’s validation/policy gate. Plain dependencies keep resolving against crates.io, unchanged from today.

SparseMirror

The chain terminated at a sparse+https:// index (FR-005).

Fields

index: RegistryIndex

The validated, fetchable mirror index.

auth: Option<AuthToken>

The bearer token to attach to requests against index, if any — populated only when the whole chain’s IndexTrust folded to IndexTrust::Trusted (plan-1b §1.4’s “coupled trust trap” guard): a single workspace-tier link anywhere in the chain forces this to None, even if the terminal itself is a $CARGO_HOME [registries] entry carrying a token.

Trait Implementations

impl Clone for SourceReplacement

fn clone(&self) -> SourceReplacement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceReplacement

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

Formats the value using the given formatter.

impl PartialEq for SourceReplacement

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