Typed shard key value to avoid string parsing overhead.

Use typed variants when possible for better performance. String variants are provided for complex types that require parsing.

​
Performance Notes

  • Numeric types (Int, Long, Float, Double, Boolean, Int8, Int16) are Copy and zero-cost
  • String references (String, Date, Ipv4, Decimal, etc.) are borrowed - no allocation
  • All variants are Copy for zero-cost passing

​
Variants

​
Int(i32)

32-bit integer value

​
Long(i64)

64-bit integer value

​
Float(f32)

32-bit float value

​
Double(f64)

64-bit double value

​
String(&‘a str)

String value (also used for char(N) types) - borrowed reference

​
Date(&‘a str)

Date in YYYY-MM-DD format - borrowed reference

​
Ipv4(&‘a str)

IPv4 in dotted-quad format (e.g., “192.168.1.100”) - borrowed reference

​
Decimal(&‘a str)

Decimal as string (e.g., “12345.6789”) - borrowed reference

​
Boolean(bool)

Boolean value (true/false)

​
Int8(i8)

8-bit signed integer (-128 to 127)

​
Int16(i16)

16-bit signed integer (-32768 to 32767)

​
Timestamp(i64)

Timestamp as milliseconds since Unix epoch

​
DateTime(&‘a str)

DateTime in YYYY-MM-DD HH:MM:SS.mmm format - borrowed reference

​
Time(&‘a str)

Time in HH:MM:SS.mmm format - borrowed reference

​
Uuid(&‘a str)

UUID in standard format (e.g., “550e8400-e29b-41d4-a716-446655440000”) - borrowed reference

​
Ulong(&‘a str)

Unsigned long as string (0 to 18446744073709551615) - borrowed reference

​
Null

A null value, for a column of any type. It encodes as zero bytes in the width of the column’s encoding.
