Trait IdentityVault 

pub trait IdentityVault {
    type Error;

    // Required methods
    fn load(
        &self,
        label: &IdentityLabel,
    ) -> Result<Option<Zeroizing<[u8; 64]>>, Self::Error>;
    fn store(
        &mut self,
        label: &IdentityLabel,
        secret: &[u8; 64],
    ) -> Result<(), Self::Error>;
    fn remove(&mut self, label: &IdentityLabel) -> Result<Removal, Self::Error>;
    fn stored_blob_len(
        &self,
        label: &IdentityLabel,
    ) -> Result<Option<usize>, Self::Error>;
    fn load_blob<'b>(
        &self,
        label: &IdentityLabel,
        buf: &'b mut [u8],
    ) -> Result<Option<&'b [u8]>, Self::Error>;
    fn store_blob(
        &mut self,
        label: &IdentityLabel,
        blob: &[u8],
    ) -> Result<(), Self::Error>;
}

Identity secrets are fixed 64-byte entries; blobs are variable-length secret records (self-ratchet state) sharing the same trust domain and label namespace, so remove clears either kind and a label addresses exactly one entry of one kind.

Required Associated Types

type Error

Required Methods

fn load( &self, label: &IdentityLabel, ) -> Result<Option<Zeroizing<[u8; 64]>>, Self::Error>

fn store( &mut self, label: &IdentityLabel, secret: &[u8; 64], ) -> Result<(), Self::Error>

fn remove(&mut self, label: &IdentityLabel) -> Result<Removal, Self::Error>

fn stored_blob_len( &self, label: &IdentityLabel, ) -> Result<Option<usize>, Self::Error>

fn load_blob<'b>( &self, label: &IdentityLabel, buf: &'b mut [u8], ) -> Result<Option<&'b [u8]>, Self::Error>

A buf shorter than the stored blob is the impl’s error, never a silent truncation.

fn store_blob( &mut self, label: &IdentityLabel, blob: &[u8], ) -> Result<(), Self::Error>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
