DecimalCast

A utility trait that provides checked conversions between decimal types inspired by NumCast

Functions

apply_decimal_cast 🔒

apply_rescaler 🔒

Apply the rescaler function to the value. If the rescaler is infallible, use the infallible function. Otherwise, use the fallible function and validate the precision.

cast_decimal_to_decimal 🔒

cast_decimal_to_decimal_error 🔒

cast_decimal_to_decimal_same_type 🔒

cast_decimal_to_float 🔒

Cast a decimal array to a floating point array.

cast_decimal_to_integer 🔒

cast_floating_point_to_decimal 🔒

cast_string_to_decimal 🔒

Cast Utf8 to decimal

convert_to_bigger_or_equal_scale_decimal 🔒

convert_to_smaller_scale_decimal 🔒

generic_string_to_decimal_cast 🔒

make_downscaler 🔒

Construct closures to downscale decimals from (input_precision, input_scale) to (output_precision, output_scale).

make_upscaler 🔒

Construct closures to upscale decimals from (input_precision, input_scale) to (output_precision, output_scale).

parse_string_to_decimal_native 🔒

Parses given string to specified decimal native (i128/i256) based on given scale. Returns an Err if it cannot parse given string.

rescale_decimal

Rescales a decimal value from (input_precision, input_scale) to (output_precision, output_scale) and returns the converted number when it fits within the output precision.
