Struct Backend 

pub struct Backend { /* private fields */ }

Implementations

impl Backend

pub async fn init<P: AsRef<Path>>(home: P, default: bool) -> Result<Self>

Initializes an openpgp card backend.

home is the directory where the backend will look for its configuration, e.g., $HOME/.sq/keystore/openpgp-card.

If default is true, this backend uses the cards managed by PCSC. Otherwise, the backend is disabled.

pub async fn init_ephemeral() -> Result<Self>

Initializes an ephemeral OpenPGP card backend.

This is primarily useful for testing.

Trait Implementations

impl Backend for Backend

fn id(&self) -> String

Returns the backend’s identifier.

fn scan<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Causes the backend to look for devices.

fn list<'a, 'async_trait>( &'a self, ) -> Pin<Box<dyn Future<Output = Box<dyn Iterator<Item = Box<dyn DeviceHandle + Send + Sync + 'a>> + Send + Sync + 'a>> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait,

Lists all devices that are available or registered.

fn find_device<'a, 'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn DeviceHandle + Send + Sync + 'a>>> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns a handle for the specified device.

fn find_key<'a, 'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn KeyHandle + Send + Sync + 'a>>> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns a handle for the specified key.

fn import<'a, 'life0, 'async_trait>( &'life0 self, _cert: Cert, ) -> Pin<Box<dyn Future<Output = Result<Vec<(ImportStatus, Box<dyn KeyHandle + Send + Sync + 'a>)>>> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait,

Imports the keys in the cert.

impl Clone for Backend

fn clone(&self) -> Backend

Returns a duplicate of the value.

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

Performs copy-assignment from source.
