Enum ExportKind 

pub enum ExportKind {
    Cargo,
    CratesVendor,
    BazelRegistry,
    BazelDistdir,
    Vsix,
    Sdk,
}

Which export adapter an [[export]] entry names (REQ-EXPORTDECL-001 clause 2).

The wire strings are exactly the ones the adapters already write into .varve-export.json, so a declaration and the stamp it is checked against are comparable without a translation table — a table is a place for the two to drift, and drift here would make verify pass on a directory produced by a different adapter entirely.

Implementations

impl ExportKind

pub const ALL: &'static [ExportKind]

Every kind, for diagnostics that must say what WOULD have worked.

pub fn as_str(self) -> &'static str

pub fn is_sourced(self) -> bool

Is this payload CONSUMED by entering an environment rather than by pointing at a path (clause 4)?

A Yocto SDK is sourced: environment-setup-* sets CC, SYSROOT and CFLAGS and prepends its own bin to PATH. A local Cargo registry or a distdir is not — a config file points at it. Only a sourced export may carry an [export.env], because on anything else the block would be accepted, ignored, and believed.
