Struct OdbcValue 

pub struct OdbcValue { /* private fields */ }

A small owned ODBC value representation used by unit tests and Any-mapping work.

Implementations

impl OdbcValue

pub fn new(kind: OdbcValueKind) -> Self

Creates a new value from a raw kind.

pub fn kind(&self) -> &OdbcValueKind

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 OdbcValue

fn clone(&self) -> OdbcValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OdbcValue

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

Formats the value using the given formatter.

impl PartialEq for OdbcValue

fn eq(&self, other: &OdbcValue) -> 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 Value for OdbcValue

type Database = Odbc

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

Get this value as a reference.

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

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.
