Struct CharDataType 

pub struct CharDataType {
    pub length: u32,
    pub encoding: StringEncoding,
}

Fixed-length character string.

Maps to: CHAR(n) (PostgreSQL, SQL Server, Snowflake), FixedString(n) (ClickHouse). Note: Databricks does not have a fixed-length char type.

Example

use razeri_plugin_contract::data_type::{CharDataType, StringEncoding};

// Default: Unicode encoding
let char_type = CharDataType::new(50);
assert_eq!(char_type.length, 50);

// Explicit ASCII encoding
let ascii_char = CharDataType::with_encoding(10, StringEncoding::Ascii);

Fields

length: u32

Fixed length in characters (1-8000 for SQL Server, 1-16777216 for Snowflake).

encoding: StringEncoding

Character encoding (default: Unicode).

Implementations

impl CharDataType

pub fn new(length: u32) -> Self

Creates a fixed-length character string with Unicode encoding.

Example

use razeri_plugin_contract::data_type::CharDataType;

let char = CharDataType::new(100);
assert_eq!(char.length, 100);

pub fn with_encoding(length: u32, encoding: StringEncoding) -> Self

Creates a fixed-length character string with the specified encoding.

Example

use razeri_plugin_contract::data_type::{CharDataType, StringEncoding};

let ascii = CharDataType::with_encoding(20, StringEncoding::Ascii);
assert_eq!(ascii.encoding, StringEncoding::Ascii);
