Struct SingleTenantResolver 

pub struct SingleTenantResolver { /* private fields */ }

Reference impl: always resolve to one fixed tenant.

The explicit opt-out for single-user dev installs that want tenancy off (or for deployments that want a deliberately single-tenant posture). The opt-out is grep-able in the hub builder code: a reviewer searching for SingleTenantResolver finds every deployment that has consciously disabled multi-tenancy.

Implementations

impl SingleTenantResolver

pub fn new() -> Self

Construct with the literal tenant value "default".

Panics only if "default" fails Tenant::try_new validation — which it cannot (non-empty, short, all printable ASCII). Encoded as expect so a future change to the validation rules surfaces the failure here rather than silently shipping a non-functional resolver.

pub fn with_fixed(value: impl Into<String>) -> Result<Self, TenantError>

Construct with a custom fixed tenant identifier.

Returns an error if the candidate fails Tenant::try_new validation (empty, too long, non-printable bytes). The pub(crate) reach to the constructor is acceptable here because this builder is itself part of plexus-auth-core’s blessed API: a backend operator who calls with_fixed("acme") is explicitly opting in to a fixed tenant value at hub configuration time, exactly as AUTHZ-DATA-S01-output §2 describes (“the opt-out is explicit and grep-able”).
