func Uint64Checked ¶

func Uint64Checked(s string) (uint64, error)

Uint64Checked parses a uint64 from a string that may have been serialized from a Daml NUMERIC.

Daml NUMERIC values are decimal strings with arbitrary precision, and may be represented with a trailing decimal point (for example "12345."). In this codebase we only accept integer-valued NUMERICs when converting into uint64.

The parsing is strict: - the value must parse as a rational number - it must be an integer (no fractional component) - it must fit into an unsigned 64-bit integer
