Module copy 

PostgreSQL COPY statement envelopes and stream codecs.

COPY FROM STDIN and COPY TO STDOUT carry their byte stream outside the SQL statement. The regular crate::compile entry point therefore cannot execute one by itself; callers use compile_copy to validate the SQL envelope and pair it with the stream through the engine COPY API.

Structs

CopyOptions

Parsed COPY options after format-dependent defaults have been applied.

CopyStatement

Fully validated COPY statement envelope.

Enums

CopyDirection

COPY stream direction.

CopyEndpoint

Where PostgreSQL expects the COPY stream to be connected.

CopyFormat

COPY data encoding implemented by the embedded stream API.

CopyHeader

PostgreSQL’s three HEADER states.

CopyTarget

The relation or query supplying COPY rows.

Functions

compile_copy

Parse exactly one PostgreSQL COPY statement.

decode_copy_input

Decode a complete text or CSV COPY stream into rows.

encode_copy_result

Encode one SQL result using PostgreSQL COPY text or CSV representation.

encode_copy_result_with_engine

Encode one SQL result while resolving catalog-backed reg* text output through the engine hook.

Type Aliases

CopyInputField

One decoded COPY field. None is SQL NULL; strings remain in PostgreSQL’s textual input representation so the target column’s normal input coercion remains authoritative.
