Enum SqlType 

#[non_exhaustive]
#[repr(i8)]
pub enum SqlType {
    Int = 2,
    Real = 1,
    String = 0,
    Decimal = 4,
}

Enum representing possible SQL result types

This simply represents the possible types, but does not contain any values. SqlResult is the corresponding enum that actually contains data.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Int = 2

Integer result

Real = 1

Real result

String = 0

String result

Decimal = 4

Decimal result

Implementations

impl SqlType

pub fn to_item_result(&self) -> Item_result

Convert this enum to a SQL Item_result. This is only useful if you work with udf_sys bindings directly.

pub fn display_name(&self) -> &'static str

Small helper function to get a displayable type name.

Trait Implementations

impl Clone for SqlType

fn clone(&self) -> SqlType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqlType

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

Formats the value using the given formatter.

impl PartialEq for SqlType

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

impl TryFrom<&SqlResult<'_>> for SqlType

fn try_from(tag: &SqlResult<'_>) -> Result<Self, Self::Error>

Create an SqlType from an SqlResult

type Error = String

The type returned in the event of a conversion error.

impl TryFrom<Item_result> for SqlType

fn try_from(tag: Item_result) -> Result<Self, Self::Error>

Create an SqlType from an Item_result, located in the bindings module.

type Error = String

The type returned in the event of a conversion error.

impl TryFrom<i8> for SqlType

fn try_from(tag: i8) -> Result<Self, Self::Error>

Create an SqlType from an integer

type Error = String

The type returned in the event of a conversion error.

impl Copy for SqlType

impl Eq for SqlType

impl StructuralPartialEq for SqlType
