Struct AppSeed 

pub struct AppSeed(/* private fields */);

The 32-byte per-app seed the security element derives for a calling app.

A distinct type (annotated like Seed) so the zeroize-on-drop treatment follows the bytes wherever an AppSeed flows, and a call site can’t quietly pass an unrelated array where a seed is expected. Raw [u8; 32] copies a caller makes from as_bytes still escape scrubbing (Rust move semantics), so this narrows the exposure window rather than closing it.

Implementations

impl AppSeed

pub fn new(bytes: [u8; 32]) -> Self

Permission: not needed

pub fn as_bytes(&self) -> &[u8; 32]

Permission: not needed

Trait Implementations

impl Archive for AppSeed

where [u8; 32]: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedAppSeed

The archived representation of this type.

type Resolver = AppSeedResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for AppSeed

fn clone(&self) -> AppSeed

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<__D: Fallible + ?Sized> Deserialize<AppSeed, __D> for Archived<AppSeed>

where [u8; 32]: Archive, <[u8; 32] as Archive>::Archived: Deserialize<[u8; 32], __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<AppSeed, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Drop for AppSeed

fn drop(&mut self)

Executes the destructor for this type.

impl<__S: Fallible + ?Sized> Serialize<__S> for AppSeed

where [u8; 32]: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
