Trait Implementations

impl Clone for OdbcTypeInfo

fn clone(&self) -> OdbcTypeInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OdbcTypeInfo

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

Formats the value using the given formatter.

impl Display for OdbcTypeInfo

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

Formats the value using the given formatter.

impl PartialEq for OdbcTypeInfo

fn eq(&self, other: &OdbcTypeInfo) -> 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<'a> TryFrom<&'a OdbcTypeInfo> for AnyTypeInfo

type Error = Error

The type returned in the event of a conversion error.

fn try_from(type_info: &'a OdbcTypeInfo) -> Result<Self, Self::Error>

Performs the conversion.

impl TypeInfo for OdbcTypeInfo

fn is_null(&self) -> bool

fn name(&self) -> &str

Returns the database system name of the type. Length specifiers should not be included. Common type names are VARCHAR, TEXT, or INT. Type names should be uppercase. They should be a rough approximation of how they are written in SQL in the given database.

fn type_compatible(&self, other: &Self) -> bool

where Self: Sized,

Return true if self and other represent mutually compatible types.
