Struct opendal::services::PostgresqlConfig

#[non_exhaustive]
pub struct PostgresqlConfig {
    pub root: Option<String>,
    pub connection_string: Option<String>,
    pub table: Option<String>,
    pub key_field: Option<String>,
    pub value_field: Option<String>,

Config for PostgreSQL services support.

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.

root: Option<String>

Root of this backend.

All operations will happen under this root.

Default to / if not set.

connection_string: Option<String>

The URL should be with a scheme of either postgres:// or postgresql://.

• postgresql://user@localhost
• postgresql://user:password@%2Fvar%2Flib%2Fpostgresql/mydb?connect_timeout=10
• postgresql://user@host1:1234,host2,host3:5678?target_session_attrs=read-write
• postgresql:///mydb?user=user&host=/var/lib/postgresql

table: Option<String>

the table of postgresql

key_field: Option<String>

the key field of postgresql

value_field: Option<String>

the value field of postgresql

Trait Implementations

impl Clone for PostgresqlConfig

fn clone(&self) -> PostgresqlConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Configurator for PostgresqlConfig

Available on crate feature services-postgresql only.

type Builder = PostgresqlBuilder

Associated builder for this configuration.

fn into_builder(self) -> Self::Builder

Convert this configuration into a service builder.

fn from_iter(iter: impl IntoIterator<Item = (String, String)>) -> Result<Self>

Deserialize from an iterator.

impl Debug for PostgresqlConfig

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

Formats the value using the given formatter.

impl Default for PostgresqlConfig

fn default() -> PostgresqlConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PostgresqlConfig

where PostgresqlConfig: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PostgresqlConfig

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

impl Serialize for PostgresqlConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for PostgresqlConfig

impl StructuralPartialEq for PostgresqlConfig
