Struct PdRouterContext

#[repr(C)]
pub struct PdRouterContext {
    pub shards: u64,
    pub has_replicas: u8,
    pub has_primary: u8,
    pub in_transaction: u8,
    pub write_override: u8,
    pub query: PdStatement,
    pub params: PdParameters,
}

Context on the database cluster configuration and the currently processed PostgreSQL statement.

This struct is C FFI-safe and therefore uses C types. Use public methods to interact with it instead of reading the data directly.

Fields

shards: u64

How many shards are configured.

has_replicas: u8

Does the database cluster have replicas? 1 = true, 0 = false.

has_primary: u8

Does the database cluster have a primary? 1 = true, 0 = false.

in_transaction: u8

Is the query being executed inside a transaction? 1 = true, 0 = false.

write_override: u8

PgDog strongly believes this statement should go to a primary. 1 = true, 0 = false.

query: PdStatement

pg_query generated Abstract Syntax Tree of the statement.

params: PdParameters

Bound parameters.
