Struct TimeDataType 

pub struct TimeDataType {
    pub precision: Option<u8>,
    pub with_timezone: bool,
}

Time only without date component.

Maps to: TIME (PostgreSQL, SQL Server, Snowflake), not directly supported in ClickHouse/Databricks.

Precision

• PostgreSQL: 0-6
• SQL Server: 0-7
• Snowflake: 0-9
• ClickHouse: 0-9

Example

use razeri_plugin_contract::data_type::TimeDataType;

// Default precision: 6, no timezone
let time = TimeDataType::default();
assert_eq!(time.precision, Some(6));
assert!(!time.with_timezone);

// Precision 3, with timezone
let tz_time = TimeDataType::with_timezone(3);
assert_eq!(tz_time.precision, Some(3));
assert!(tz_time.with_timezone);

Fields

precision: Option<u8>

The digits of a second a time keeps, where the design states them: Some(0) is whole seconds, Some(3) milliseconds. None is a bare time, which keeps whatever the engine’s own time keeps — a dialect spells it without a precision, or with the one it has always written.

with_timezone: bool

Whether to include timezone offset.

Maps to: TIME WITH TIME ZONE (PostgreSQL), not supported in SQL Server.

Implementations

impl TimeDataType

pub fn new(precision: u8) -> Self

Creates a new TimeDataType with the given fractional seconds precision.

Panics

Panics if precision exceeds 9.

Example

use razeri_plugin_contract::data_type::TimeDataType;

let time = TimeDataType::new(3);
assert_eq!(time.precision, Some(3));
assert!(!time.with_timezone);

use razeri_plugin_contract::data_type::TimeDataType;

let _ = TimeDataType::new(10); // panics: precision must be 0-9

pub const fn engines_own() -> Self

A bare time: no digits of a second stated, so the engine’s own time keeps whatever it keeps.

pub fn with_timezone(precision: u8) -> Self

Creates a TimeDataType with timezone and the given precision.

Panics

Panics if precision exceeds 9.

Example

use razeri_plugin_contract::data_type::TimeDataType;

let tz_time = TimeDataType::with_timezone(3);
assert_eq!(tz_time.precision, Some(3));
assert!(tz_time.with_timezone);
