Struct ClassMemberTrace 

pub struct ClassMemberTrace {
    pub file: PathBuf,
    pub member_name: String,
    pub member_kind: String,
    pub owner_export: String,
    pub owner_is_used: bool,
    pub owner_file_reachable: bool,
    pub owner_is_entry_point: bool,
    pub owner_direct_references: Vec<ExportReference>,
    pub owner_re_export_chains: Vec<ReExportChain>,
    pub reason: String,
}

Result of tracing a class / enum / store MEMBER: the --trace FILE:NAME fallback when NAME is not a top-level export but a member declared on one (issue #1744). The trace runs on the module graph only, so it reports the OWNING export’s reachability and usage (the gating precondition for member-level crediting) plus a pointer to the right --unused-*-members command, rather than per-member crediting provenance.

Fields

file: PathBuf

The file containing the member.

member_name: String

The member name being traced.

member_kind: String

The member kind: class-method, class-property, enum-member, store-member, or namespace-member.

owner_export: String

The export that declares this member (the class / enum / store name).

owner_is_used: bool

Whether the owning export is considered used.

owner_file_reachable: bool

Whether the file is reachable from an entry point.

owner_is_entry_point: bool

Whether the file is an entry point.

owner_direct_references: Vec<ExportReference>

Files that reference the owning export directly.

owner_re_export_chains: Vec<ReExportChain>

Re-export chains through which the owning export is reachable. Populated so a machine consumer can tell “used via a barrel” (empty direct refs but non-empty chains) from “genuinely unreferenced”.

reason: String

Human-readable reason summary plus the follow-up command to inspect the member finding.
