Crate plrust_trusted_pgrx

plrust-trusted-pgrx is a re-export crate based on pgrx which exposes the minimal set of pgrx internals necessary for plrust function compilation. plrust-trusted-pgrx also includes a number of Rust types for interoperating with Postgres types, access to Postgres’ “SPI”, logging, and trigger support.

Re-exports

• pub use datum::*;
• pub use heap_tuple::*;
• pub use iter::*;
• pub use pg_sys::*;
• pub use trigger_support::*;

Modules

• datum
  Safe Rust wrappers for various Postgres types.
• fn_call
• heap_tuple
  Support for arbitrary composite types as a “heap tuple”.
• iter
  Return iterators from plrust functions
• pg_sys
  Lower-level Postgres internals, which are safe to use.
• prelude
  Use all the things.
• spi
  Use Postgres’ Server Programming Interface to execute arbitrary SQL.
• trigger_support
  Various types for use when a plrust function is a trigger function.

Macros

• debug1
  Log to Postgres’ debug1 log level.
• debug2
  Log to Postgres’ debug2 log level.
• debug3
  Log to Postgres’ debug3 log level.
• debug4
  Log to Postgres’ debug4 log level.
• debug5
  Log to Postgres’ debug5 log level.
• ereport
  Sends some kind of message to Postgres, and if it’s a PgLogLevel::ERROR or greater, Postgres’ error handling takes over and, in the case of PgLogLevel::ERROR, aborts the current transaction.
• error
  Log to Postgres’ error log level. This will abort the current Postgres transaction.
• info
  Log to Postgres’ info log level.
• log
  Log to Postgres’ log log level.
• notice
  Log to Postgres’ notice log level.
• warning
  Log to Postgres’ warning log level.

Structs

• Spi

Enums

• Arg
  The kinds of fn_call arguments.
• FnCallError
  FnCallErrors represent the set of conditions that could case fn_call() to fail in a user-recoverable manner.

Traits

• ErrorReportable
  Indicates that something can be reported as a Postgres ERROR, if that’s what it might represent.
• FnCallArg
  Augments types that can be used as fn_call arguments. This is only implemented for the Arg enum.

Functions

• fn_call
  Dynamically call a named function in the current database. The function must be one previously defined by CREATE FUNCTION. Its underlying LANGUAGE is irrelevant – call LANGUAGE sql, LANGUAGE plpgsql, LANGUAGE plperl, or (our favorite) LANGUAGE plrust functions.
