Struct MssqlValue 

pub struct MssqlValue { /* private fields */ }

A small owned MSSQL ODBC value representation.

Implementations

impl MssqlValue

pub fn new(kind: MssqlValueKind) -> MssqlValue

Creates a new value from a raw kind.

pub fn kind(&self) -> &MssqlValueKind

Returns the raw value kind.

pub fn is_null(&self) -> bool

Returns whether this value is NULL.

pub fn as_i64(&self) -> Option<i64>

Returns this value as a signed integer where possible.

pub fn as_f64(&self) -> Option<f64>

Returns this value as f64 where possible.

pub fn as_str(&self) -> Option<Cow<'_, str>>

Returns this value as text where possible.

pub fn as_bytes(&self) -> Option<Cow<'_, [u8]>>

Returns this value as bytes where possible.

Trait Implementations

impl Clone for MssqlValue

fn clone(&self) -> MssqlValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MssqlValue

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

Formats the value using the given formatter.

impl PartialEq for MssqlValue

fn eq(&self, other: &MssqlValue) -> 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 StructuralPartialEq for MssqlValue

impl Value for MssqlValue

type Database = Mssql

fn as_ref(&self) -> <<MssqlValue as Value>::Database as Database>::ValueRef<'_>

Get this value as a reference.

fn type_info(&self) -> Cow<'_, MssqlTypeInfo>

Get the type information for this value.

fn is_null(&self) -> bool

Returns true if the SQL value is NULL.

fn decode<'r, T>(&'r self) -> T

where T: Decode<'r, Self::Database> + Type<Self::Database>,

Decode this single value into the requested type.

fn decode_unchecked<'r, T>(&'r self) -> T

where T: Decode<'r, Self::Database>,

Decode this single value into the requested type.

fn try_decode<'r, T>(&'r self) -> Result<T, Error>

where T: Decode<'r, Self::Database> + Type<Self::Database>,

Decode this single value into the requested type.

fn try_decode_unchecked<'r, T>(&'r self) -> Result<T, Error>

where T: Decode<'r, Self::Database>,

Decode this single value into the requested type.
