Struct SourceCursorReader 

Source 
pub struct SourceCursorReader { /* private fields */ }
Expand description

A live PostgreSQL connection pool for reading source cursors.

Implementations§

Source§

impl SourceCursorReader

Source

pub async fn connect(db_url: &str, tls: &PostgresTlsConfig) -> Result<Self>

Connect to db_url (PostgreSQL only) for cursor reads.

§Errors

Returns an error if db_url is not a PostgreSQL connection string (see crate::connection::require_postgres), the server cannot be reached, or it is older than PostgreSQL 18.

Source

pub async fn load_cursors(&self) -> Result<Vec<CursorRow>>

Load every source cursor row.

The age is computed in SQL against the database clock. cursor_value (JSONB) decodes directly to a serde_json::Value (the with-serde_json-1 codec). Missing table ⇒ an empty result is not silently returned — the error surfaces so the operator learns the source subsystem was never initialized.

§Errors

Returns an error if the connection or the query fails.
