from super::Valuemz_repr::Datum interval jsonb numeric record unsigned TextEncodeSettings Session settings that affect how values are encoded as text. Value A PostgreSQL datum. FLOAT4_DIGITS 🔒 The number of significant decimal digits that survive a round trip through
f32 and f64 respectively. FLOAT8_DIGITS 🔒 REGPROC_NULL 🔒 The text PostgreSQL’s regprocout emits for OID 0, and that regprocin
reads back as OID 0. decode_binary_string 🔒 Decodes a binary-format string value, rejecting embedded NUL characters. encode_element 🔒 format_float_limited 🔒 Formats f with ndig significant digits like C’s %.*g, mirroring
PostgreSQL’s float4out/float8out when extra_float_digits is zero or
negative. Like PostgreSQL, ndig values below 1 are clamped to 1, and
non-finite values are spelled NaN, Infinity, and -Infinity. is_number_shaped 🔒 Whether s is shaped like a decimal number, ignoring whether it is in range. parse_regproc 🔒 Parses the text format of a regproc, matching PostgreSQL’s regprocin. pg_len 🔒 reject_nul 🔒 Returns an error if s contains a NUL character, which PostgreSQL rejects
in text values. rescale_numeric 🔒 Rescales n to the scale required by constraints, if any. values_from_row Converts a Materialize row into a vector of PostgreSQL values.
