#[non_exhaustive]

Information about a connection

This is a return value of Connection::info().

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

db_domain: String

The name of the Oracle Database Domain name associated with the connection

This is the same value returned by the SQL expression SELECT VALUE FROM V$PARAMETER WHERE NAME = 'db_domain'.

db_name: String

The Oracle Database name associated with the connection

This is the same value returned by the SQL expression SELECT NAME FROM V$DATABASE. Note the values may have different cases.

instance_name: String

The Oracle Database instance name associated with the connection

This is the same value returned by the SQL expression SELECT SYS_CONTEXT('USERENV', 'INSTANCE_NAME') FROM DUAL. Note the values may have different cases.

service_name: String

The Oracle Database service name associated with the connection

This is the same value returned by the SQL expression SELECT SYS_CONTEXT('USERENV', 'SERVICE_NAME') FROM DUAL.

max_identifier_length: u32

The maximum length of identifiers (in bytes) supported by the database to which the connection has been established

See Database Object Naming Rules.

max_open_cursors: u32

The maximum number of cursors that can be opened

This is the same value returned by the SQL expression SELECT VALUE FROM V$PARAMETER WHERE NAME = 'open_cursors'.

server_type: ServerType

The type of server process used by the connection

This is only available with Oracle Client libraries 23.4 or higher. Otherwise, it is always ServerType::Unknown.

Trait Implementations

impl Clone for Info

fn clone(&self) -> Info

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Info

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

Formats the value using the given formatter.

impl PartialEq for Info

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

Tests for self and other values to be equal, and is used by ==.

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

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