Module codec 

Binary encode/decode for PostgreSQL types.

All decoding operates on raw byte slices (from the arena or wire buffer). Encoding appends big-endian bytes to a Vec<u8>.

PostgreSQL binary format is big-endian for all numeric types.

Traits

Encode

Encode a Rust value into PostgreSQL binary format.

Functions

decode_array_bool

Decode a PG binary array of booleans.

decode_array_bytea

decode_array_f32

Decode a PG binary array of f32.

decode_array_f64

Decode a PG binary array of f64.

decode_array_i16

decode_bytes

Decode raw bytes (bytea) — identity function, zero-copy.

decode_f32

decode_f64

Decode a 64-bit float from binary format (8 bytes, big-endian IEEE 754).

decode_i16

Decode a 16-bit integer from binary format (2 bytes, big-endian).

decode_i32

Decode a 32-bit integer from binary format (4 bytes, big-endian).

decode_i64

Decode a 64-bit integer from binary format (8 bytes, big-endian).

decode_str

Decode a UTF-8 string from binary format (variable length).

decode_uuid

Decode a UUID from binary format (exactly 16 bytes).

encode_param

Encode a parameter value into the wire buffer with its 4-byte length prefix.
