Module scalars 

Strict decimal ↔ scaled-integer codecs.

Constants

INT64_MAX

INT64_MIN

LEDGER_SCALE

MAX_PROTOCOL_SCALE

Maximum accepted quantity/ledger scale for public formatters and catalog hydration.

PRICE_TICK_SCALE

UINT64_MAX

Functions

decimal_to_scaled

decimal_to_scaled_str

format_id

format_ledger_u64

Format a smaller ledger quantity integer by 10^scale.

format_ledger_u128

Format a full-width unsigned ledger integer string by 10^scale.

format_price_ticks

format_qty_scaled

format_uint64_id

Format a uint64 id as base58, or "0" when zero (order/trade ids).

i128_to_u128

Encode a non-negative scaled integer as protobuf U128 (hi/lo).

id_to_u64

Parse a public id that may be base58 or decimal.

parse_decimal_input

parse_price_ticks

parse_price_ticks_str

parse_qty_scaled

parse_qty_scaled_str

try_decimal_to_scaled

Strict decimal→scaled. Never rounds; excess fractional digits fail.

u128_to_proto

Encode a u128 as protobuf U128 (hi/lo).

u128_to_str

Format protobuf U128 hi/lo as a decimal string.

validate_protocol_scale

Validate a caller/catalog scale before padding or allocation.
