Enum odbc_sys::AttrCpMatch

#[repr(u32)]
pub enum AttrCpMatch {
    Strict,
    Relaxed,
}

Determines how a connection is chosen from a connection pool.

Possible values for CpMatch attribute set with crate::SQLSetEnvAttr to define which connection attributes must match for a connection returned from the pool

Variants

Strict

Only connections that exactly match the connection options in the call and the connection attributes set by the application are reused. This is the default.

Relaxed

Connections with matching connection string keywords can be used. Keywords must match, but not all connection attributes must match.

Trait Implementations

impl Clone for AttrCpMatch

fn clone(&self) -> AttrCpMatch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AttrCpMatch

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

Formats the value using the given formatter.

impl Default for AttrCpMatch

Default matching for connections returned from the pool

fn default() -> Self

Returns the “default value” for a type.

impl From<AttrCpMatch> for Pointer

fn from(source: AttrCpMatch) -> Pointer

Converts to this type from the input type.

impl PartialEq<AttrCpMatch> for AttrCpMatch

fn eq(&self, other: &AttrCpMatch) -> 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.
