Struct ExaTypeInfo 

pub struct ExaTypeInfo { /* private fields */ }

Information about an Exasol data type and implementor of TypeInfo.

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

Manually implemented because we only want to serialize the data_type field while also flattening the structure.

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)_/¯. This is also due to Exasol’s limited number of data types. How would it look saying that a DECIMAL column does not fit in some other DECIMAL data type?

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

where Self: Sized,

Checks compatibility with other data types.

Returns true if this ExaTypeInfo instance is able to accommodate the other instance.

fn is_null(&self) -> bool

impl Copy for ExaTypeInfo
