Struct ExaTypeInfo

pub struct ExaTypeInfo { /* private fields */ }

Information about an Exasol data type and implementor of TypeInfo.

Implementations

impl ExaTypeInfo

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

Checks compatibility with other data types.

Returns true if the ExaTypeInfo instance is compatible/bigger/able to accommodate the other instance.

Trait Implementations

impl Clone for ExaTypeInfo

fn clone(&self) -> ExaTypeInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExaTypeInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExaTypeInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ExaTypeInfo

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

Formats the value using the given formatter.

impl PartialEq for ExaTypeInfo

fn eq(&self, other: &Self) -> 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 Serialize for ExaTypeInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeInfo for ExaTypeInfo

fn name(&self) -> &str

We’re going against sqlx here, but knowing the full data type definition is actually very helpful when displaying error messages, so… ¯_(ツ)_/¯.

In fact, error messages seem to be the only place where this is being used, particularly when trying to decode a value but the data type provided by the database does not match/fit inside the Rust data type.

fn is_null(&self) -> bool

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

where Self: Sized,

Return true if self and other represent mutually compatible types.
