[−][src]Struct hdbconnect::ConnectParamsBuilder
A builder for ConnectParams
.
Example
use hdbconnect::ConnectParams; let connect_params = ConnectParams::builder() .hostname("abcd123") .port(2222) .dbuser("MEIER") .password("schlau") .build() .unwrap();
Instantiating a ConnectParamsBuilder
from a URL
The URL is supposed to have the same form as for ConnectParams
(i.e. <scheme>://<username>:<password>@<host>:<port>[<options>]
,
see Using a URL),
but only scheme and host
are mandatory.
Example
use hdbconnect::IntoConnectParamsBuilder; let conn_params = "hdbsql://abcd123:2222" .into_connect_params_builder() .unwrap() .dbuser("MEIER") .password("schlau") .build() .unwrap();
Methods
impl ConnectParamsBuilder
[src]
pub fn new() -> Self
[src]
Creates a new builder.
pub fn hostname<H: AsRef<str>>(&mut self, hostname: H) -> &mut Self
[src]
Sets the hostname.
pub fn port(&mut self, port: u16) -> &mut Self
[src]
Sets the port.
pub fn dbuser<D: AsRef<str>>(&mut self, dbuser: D) -> &mut Self
[src]
Sets the database user.
pub fn password<P: AsRef<str>>(&mut self, pw: P) -> &mut Self
[src]
Sets the password.
pub fn clientlocale<P: AsRef<str>>(&mut self, cl: P) -> &mut Self
[src]
Sets the client locale.
pub fn clientlocale_from_env_lang(&mut self) -> &mut Self
[src]
Sets the client locale from the value of the environment variable LANG
pub fn tls_with(&mut self, server_certs: ServerCerts) -> &mut Self
[src]
Makes the driver use TLS for the connection to the database.
Requires that the server's certificate is provided with one of the
enum variants of ServerCerts
.
If needed, you can call this function multiple times with different ServerCert
variants.
Example:
let mut conn_params = ConnectParams::builder() // ...more settings required... .tls_with(ServerCerts::Direct(string_with_certificate)) .build();
pub fn option(&mut self, name: &str, value: &str) -> &mut Self
[src]
Adds a runtime parameter.
pub fn build(&self) -> HdbResult<ConnectParams>
[src]
Constructs a ConnectParams
from the builder.
Errors
HdbError::Usage
if the builder was not yet configured to
create a meaningful ConnectParams
pub fn to_url(&self) -> HdbResult<String>
[src]
Returns the url for this connection
Errors
HdbError::Usage
if the builder was not yet configured to
build a correct url
