Struct ParsedSqlType 

pub struct ParsedSqlType {
    pub base_type: String,
    pub length: Option<u32>,
    pub precision: Option<u32>,
    pub scale: Option<u32>,
    pub unsigned: bool,
    pub array: bool,
}

Parsed SQL type with extracted metadata.

Fields

base_type: String

Base type name (e.g., VARCHAR, INTEGER, DECIMAL)

length: Option<u32>

Length for character types (e.g., VARCHAR(255) -> 255)

precision: Option<u32>

Precision for numeric types (e.g., DECIMAL(10,2) -> 10)

scale: Option<u32>

Scale for numeric types (e.g., DECIMAL(10,2) -> 2)

unsigned: bool

Whether the type is unsigned (MySQL)

array: bool

Whether this is an array type (PostgreSQL)

Implementations

impl ParsedSqlType

pub fn parse(type_str: &str) -> Self

Parse a SQL type string into structured metadata.

Examples

• VARCHAR(255) -> base_type: “VARCHAR”, length: 255
• DECIMAL(10,2) -> base_type: “DECIMAL”, precision: 10, scale: 2
• INT UNSIGNED -> base_type: “INT”, unsigned: true
• TEXT[] -> base_type: “TEXT”, array: true

pub fn is_text(&self) -> bool

Check if this is a text/string type.

pub fn is_numeric(&self) -> bool

Check if this is a numeric type.

pub fn is_datetime(&self) -> bool

Check if this is a date/time type.

Trait Implementations

impl Clone for ParsedSqlType

fn clone(&self) -> ParsedSqlType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParsedSqlType

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

Formats the value using the given formatter.

impl Default for ParsedSqlType

fn default() -> ParsedSqlType

Returns the “default value” for a type.

impl PartialEq for ParsedSqlType

fn eq(&self, other: &ParsedSqlType) -> 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.
