[−][src]Struct mobc::Builder

pub struct Builder<M> { /* fields omitted */ }

A builder for a connection pool.

Methods

impl<M: Manager> Builder<M>[src]

pub fn new() -> Self[src]

Constructs a new Builder.

Parameters are initialized with their default values.

pub fn max_open(self, max_open: u64) -> Self[src]

Sets the maximum number of connections managed by the pool.

0 means unlimited, defaults to 10.

pub fn max_idle(self, max_idle: u64) -> Self[src]

Sets the maximum idle connection count maintained by the pool.

The pool will maintain at most this many idle connections at all times, while respecting the value of max_open.

Defaults to 2.

pub fn max_lifetime(self, max_lifetime: Option<Duration>) -> Self[src]

Sets the maximum lifetime of connections in the pool.

Expired connections may be closed lazily before reuse.

None meas reuse forever. Defaults to None.

Panics

Panics if max_lifetime is the zero Duration.

pub fn get_timeout(self, get_timeout: Option<Duration>) -> Self[src]

Sets the get timeout used by the pool.

Calls to Pool::get will wait this long for a connection to become available before returning an error.

None meas never timeout. Defaults to 30 seconds.

Panics

Panics if connection_timeout is the zero duration

pub fn build(self, manager: M) -> Pool<M>[src]

Consumes the builder, returning a new, initialized pool.

Panics

Panics if max_idle is greater than max_size.
