Enum BackendType 

pub enum BackendType {
    InMemory,
    Filesystem(String),
    HostSql(HostSqlHandle),
}

Used when constructing the account manager

Variants

InMemory

No true synchronization will occur; data is lost between program executions. Ideal for WASM environments that don’t have filesystem access

Filesystem(String)

Synchronization will occur on the filesystem

HostSql(HostSqlHandle)

Synchronization will occur through SQL storage the host process provides

Implementations

impl BackendType

pub fn is_filesystem_backend(&self) -> bool

Returns true if this backend uses the local filesystem for storage.

pub fn stores_streamed_objects(&self) -> bool

Whether this backend stores the objects streamed to it (file transfers, RE-VFS). Nodes exchange it when they connect, and a node refuses to send a file to one that cannot.

pub fn new<T>(url: T) -> Result<BackendType, NetworkError>

where T: Into<String>,

Creates a new BackendType given the provided url. Returns an error if the URL could not be parsed

pub fn filesystem<T>(path: T) -> BackendType

where T: Into<String>,

For requesting the use of the local filesystem as a backend URL format: file:/path/to/directory (unix) or file:C\windows\dir (windows)

Trait Implementations

impl Clone for BackendType

fn clone(&self) -> BackendType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendType

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for BackendType

fn default() -> BackendType

Platform-aware default backend selection.

On native + filesystem feature: uses ~/.citadel/<uuid> directory. On WASM or without filesystem feature: uses in-memory storage.

Under localhost-testing the same kind of store goes under the OS temp dir instead. The directory is a fresh uuid on every call, so no later run ever reads it back: every test node built without a backend left one behind in the user’s home, forever – 27,000 of them, 6 GB, on one developer machine. localhost-testing is only ever enabled by dev-dependencies, so release builds keep ~/.citadel.

impl Eq for BackendType

impl PartialEq for BackendType

fn eq(&self, other: &BackendType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
