Capabilities

Depending on its configuration and the backing system, this service can expose:

• [ ] create_dir
• [x] stat
• [x] read
• [x] write
• [x] delete
• [ ] list
• [ ] copy
• [ ] rename
• [ ] presign

Inspect the effective capability set with [opendal_core::Operator::info] and [opendal_core::OperatorInfo::capability] after building an operator.

Configuration

Use [crate::PostgresqlConfig] for serializable configuration and this builder's methods for direct construction. The field and method documentation defines accepted values, defaults, and environment interaction.

Example

Via Builder

use opendal_core::Operator;
use opendal_core::Result;
use opendal_service_postgresql::Postgresql;

#[tokio::main]
async fn main() -> Result<()> {
    let mut builder = Postgresql::default()
        .root("/")
        .connection_string("postgresql://you_username:your_password@127.0.0.1:5432/your_database")
        .table("your_table")
        // key field type in the table should be compatible with Rust's &str like text
        .key_field("key")
        // value field type in the table should be compatible with Rust's Vec<u8> like bytea
        .value_field("value");

    let op = Operator::new(builder)?;
    Ok(())
}
