Struct WalPoolBuilder

pub struct WalPoolBuilder {
    pub num_read_connections: usize,
    pub reader_init_fn: Option<Arc<dyn Fn(&mut Connection) -> Result<(), Error> + Send + Sync + 'static>>,
    pub writer_init_fn: Option<Arc<dyn Fn(&mut Connection) -> Result<(), Error> + Send + Sync + 'static>>,
}

A builder for a WalPool.

Fields

num_read_connections: usize

The number of read connections

reader_init_fn: Option<Arc<dyn Fn(&mut Connection) -> Result<(), Error> + Send + Sync + 'static>>

A function to be called to initialize each reader.

writer_init_fn: Option<Arc<dyn Fn(&mut Connection) -> Result<(), Error> + Send + Sync + 'static>>

A function to be called to initialize the writer.

Implementations

impl WalPoolBuilder

pub fn new() -> Self

Make a new WalPoolBuilder.

pub fn num_read_connections(&mut self, num_read_connections: usize) -> &mut Self

Set the number of read connections.

This must be greater than 0.

pub fn writer_init_fn<F>(&mut self, writer_init_fn: F) -> &mut Self

where F: Fn(&mut Connection) -> Result<(), Error> + Send + Sync + 'static,

Add a function to be called when the writer connection initializes.

pub fn reader_init_fn<F>(&mut self, reader_init_fn: F) -> &mut Self

where F: Fn(&mut Connection) -> Result<(), Error> + Send + Sync + 'static,

Add a function to be called when a reader connection initializes.

pub async fn open<P>(&self, path: P) -> Result<WalPool, Error>

where P: AsRef<Path>,

Open the pool.

Trait Implementations

impl Default for WalPoolBuilder

fn default() -> Self

Returns the “default value” for a type.
