Struct Descriptor 

pub struct Descriptor {
    pub descriptions: Vec<Description>,
    pub load_balance: bool,
    pub failover: bool,
    pub source_route: bool,
}

A fully parsed connect string: one or more Descriptions.

Fields

descriptions: Vec<Description>

Member descriptions (one for a plain DESCRIPTION, several for a DESCRIPTION_LIST or multi-address-list EZConnect).

load_balance: bool

DESCRIPTION_LIST LOAD_BALANCE=ON.

failover: bool

DESCRIPTION_LIST FAILOVER=OFF.

source_route: bool

DESCRIPTION_LIST SOURCE_ROUTE=ON.

Implementations

impl Descriptor

pub fn first_description(&self) -> &Description

The first description (always present for a successfully parsed string).

pub fn addresses(&self) -> impl Iterator<Item = &Address>

Iterator over every Address across all descriptions, in order.

pub fn first_address(&self) -> Option<&Address>

The first address that has a host, if any.

pub fn describe(&self) -> String

Human-readable troubleshooting dump of the resolved address list and connect data — the differentiator over python-oracledb’s terse errors.

Trait Implementations

impl Clone for Descriptor

fn clone(&self) -> Descriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Descriptor

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

Formats the value using the given formatter.

impl PartialEq for Descriptor

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