Struct gotham::middleware::session::MemoryBackend

pub struct MemoryBackend { /* private fields */ }

Defines the in-process memory based session storage.

This is the default implementation which is used by NewSessionMiddleware::default()

Implementations

impl MemoryBackend

pub fn new(ttl: Duration) -> MemoryBackend

Creates a new MemoryBackend where sessions expire and are removed after the ttl has elapsed.

Alternately, MemoryBackend::default() creates a MemoryBackend with a ttl of one hour.

Examples

NewSessionMiddleware::new(MemoryBackend::new(Duration::from_secs(3600)))

Performs copy-assignment from source.

impl Default for MemoryBackend

fn default() -> MemoryBackend
