Trait KeyStore 

pub trait KeyStore {
    // Required methods
    fn save_seed(&self, seed: &[u8; 32]) -> Result<(), KeyStoreError>;
    fn load_seed(&self) -> Result<[u8; 32], KeyStoreError>;
    fn delete_seed(&self) -> Result<(), KeyStoreError>;
}

Secure storage for a 32-byte identity seed. Implement this directly for a backend other than KeyringStore (a hardware security module, a different vault) — this is the override point “per target platform” hangs off, not a platform enum this crate switches on internally.

Required Methods

fn save_seed(&self, seed: &[u8; 32]) -> Result<(), KeyStoreError>

Persist seed, overwriting any value already stored under this store’s identity.

fn load_seed(&self) -> Result<[u8; 32], KeyStoreError>

Retrieve a previously-save_seedd seed. KeyStoreError::NotFound if nothing has been stored yet.

fn delete_seed(&self) -> Result<(), KeyStoreError>

Remove a previously-stored seed, if any. Not required before a save_seed (which overwrites), only for deliberately forgetting an identity.

Dyn Compatibility

This trait is dyn compatible.

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