[Rust] BUG sbe-tool calculate wrong NULL value for uint64 fields #1025
Description
In PrimitiveValue, SBE uint64 value were represented using long type, leading to NULL value of uint64 (which is 2^64^ -1) output as -1.
This is observed in generated Rust code, and might also exists in other lang generated code.
Example:
<type name="Fixed16u64" description="Array of 16 u64" length="16" primitiveType="uint64" />
<field name="fixed16u64" id="34" type="Fixed16u64"/>Will generate something in Rust like:
/// primitive array field 'fixed16u64'
/// - min value: 0
/// - max value: -2
/// - null value: -1
/// - characterEncoding: null
/// - semanticType: null
/// - encodedOffset: 464
/// - encodedLength: 128
/// - version: 0
#[inline]
pub fn fixed_16_u64(&mut self, value: &[u64; 16]) {The generated null value in commets was -1.
