Struct splinter::registry::DieselRegistry

source · [−]

pub struct DieselRegistry<C: Connection + 'static> { /* private fields */ }

Expand description

A database-backed registry, powered by Diesel.

Implementations

source

impl<C: Connection> DieselRegistry<C>

source

pub fn new(connection_pool: Pool<ConnectionManager<C>>) -> Self

Creates a new DieselRegistry.

Arguments

connection_pool: connection pool for the database

source

pub fn new_with_write_exclusivity(
connection_pool: Arc<RwLock<Pool<ConnectionManager<C>>>>
) -> Self

Create a new DieselRegistry with write exclusivity enabled.

Write exclusivity is enforced by providing a connection pool that is wrapped in a RwLock. This ensures that there may be only one writer, but many readers.

Arguments

connection_pool: read-write lock-guarded connection pool for the database
