Struct SnowflakeColumnType 

pub struct SnowflakeColumnType { /* private fields */ }

Represents the type information of a Snowflake column.

This struct contains metadata about a column including its Snowflake data type, whether it allows NULL values, and optional size/precision/scale parameters.

Examples

use snowflake_connector_rs::SnowflakeColumnType;

// Create a text column type (VARCHAR/STRING in Snowflake)
let text_type = SnowflakeColumnType::new(
    "text".to_string(),
    true,
    Some(255),
    None,
    None
);

// Create a fixed column type (DECIMAL/NUMBER in Snowflake)
let fixed_type = SnowflakeColumnType::new(
    "fixed".to_string(),
    false,
    None,
    Some(10),
    Some(2)
);

Implementations

impl SnowflakeColumnType

pub fn new( snowflake_type: String, nullable: bool, length: Option<i64>, precision: Option<i64>, scale: Option<i64>, ) -> Self

Creates a new SnowflakeColumnType.

Arguments

• snowflake_type - The Snowflake data type name (e.g., “text”, “fixed”, “boolean”)
• nullable - Whether the column allows NULL values
• length - Optional length for character types (e.g., text with length 255)
• precision - Optional precision for numeric types (e.g., fixed(10,2))
• scale - Optional scale for numeric types (e.g., fixed(10,2))

Examples

use snowflake_connector_rs::SnowflakeColumnType;

let text_type = SnowflakeColumnType::new(
    "text".to_string(),
    true,
    Some(100),
    None,
    None
);

assert_eq!(text_type.snowflake_type(), "text");
assert_eq!(text_type.nullable(), true);
assert_eq!(text_type.length(), Some(100));

Trait Implementations

impl Clone for SnowflakeColumnType

fn clone(&self) -> SnowflakeColumnType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SnowflakeColumnType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SnowflakeColumnType

fn eq(&self, other: &SnowflakeColumnType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
