Trait Implementations

impl<'a> Clone for ColumnMetaData<'a>

fn clone(&self) -> ColumnMetaData<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ColumnMetaData<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for ColumnMetaData<'a>

fn eq(&self, other: &ColumnMetaData<'a>) -> 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, R: ThriftCompactInputProtocol<'a>> ReadThrift<'a, R> for ColumnMetaData<'a>

fn read_thrift(prot: &mut R) -> Result<Self>

Read an object of type Self from the input protocol object.

impl<'a> WriteThrift for ColumnMetaData<'a>

const ELEMENT_TYPE: ElementType = ElementType::Struct

The ElementType to use when a list of this object is written.

fn write_thrift<W: Write>( &self, writer: &mut ThriftCompactOutputProtocol<W>, ) -> Result<()>

Serialize this object to the given writer.

impl<'a> WriteThriftField for ColumnMetaData<'a>

fn write_thrift_field<W: Write>( &self, writer: &mut ThriftCompactOutputProtocol<W>, field_id: i16, last_field_id: i16, ) -> Result<i16>

Used to write struct fields (which may be primitive or IDL defined types). This will write the field marker for the given field_id, using last_field_id to compute the field delta used by the Thrift compact protocol. On success this will return field_id to be used in chaining.
