Enum odbc_sys::AttrConnectionPooling

#[repr(u32)]
pub enum AttrConnectionPooling {

Connection pool configuration

Possible values for ConnectionPooling attribute set with SQLSetEnvAttr to define which pooling scheme will be used.

See: https://docs.microsoft.com/en-us/sql/odbc/reference/syntax/sqlsetenvattr-function

Variants

Off = 0

Connection pooling is turned off. This is the default.

OnePerDriver = 1

A single connection pool is supported for each driver. Every connection in a pool is associated with one driver.

OnePerHenv = 2

A single connection pool is supported for each environment. Every connection in a pool is associated with one environment.

DriverAware = 3

Use the connection-pool awareness feature of the driver, if it is available. If the driver does not support connection-pool awareness, DriverAware is ignored and OnePerHenv is used.

Trait Implementations

impl Clone for AttrConnectionPooling

fn clone(&self) -> AttrConnectionPooling

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AttrConnectionPooling

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

Formats the value using the given formatter.

impl Default for AttrConnectionPooling

Connection pool default configuration

fn default() -> Self

Returns the “default value” for a type.

impl From<AttrConnectionPooling> for Pointer

fn from(source: AttrConnectionPooling) -> Pointer

Converts to this type from the input type.

impl PartialEq for AttrConnectionPooling

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

This method tests for self and other values to be equal, and is used by ==.

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

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