Struct ShellPiiRegistry 

pub struct ShellPiiRegistry { /* private fields */ }

Runtime-local registry of shell-scoped PII markers. Populated from the shell manifest at load time; subsequent encrypt / decrypt paths look up the marker by its wire pii_code rather than carrying a generic type parameter.

Duplicate registrations and out-of-range codes are refused; the registry is otherwise append-only (sunset flow mirrors the shell sunset policy and is out of scope for this module).

Implementations

impl ShellPiiRegistry

pub fn new() -> Self

Empty registry.

pub fn register(&mut self, entry: ShellPiiType) -> Result<(), PiiError>

Register a shell PII marker. Rejects if pii_code is outside 0x0100..=0xFFFF or has already been registered.

pub fn get(&self, pii_code: u16) -> Option<&ShellPiiType>

Look up a registered marker by its wire tag. Returns None when the code is unregistered — callers treat that as a shell drift and refuse the operation.

pub fn len(&self) -> usize

Number of registered markers.

pub fn is_empty(&self) -> bool

Whether the registry is empty.

Trait Implementations

impl Default for ShellPiiRegistry

fn default() -> ShellPiiRegistry
