Rows metadata.

Fields

flags: RowsMetadataFlags

Flags.

columns_count: i32

Number of columns.

paging_state: Option<CBytes>

Paging state.

new_metadata_id: Option<CBytesShort>

New, changed result set metadata. The new metadata ID must also be used in subsequent executions of the corresponding prepared statement, if any.

global_table_spec: Option<TableSpec>

Option that may contain global table space.

col_specs: Vec<ColSpec>

List of column specifications.

Trait Implementations

impl Clone for RowsMetadata

fn clone(&self) -> RowsMetadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RowsMetadata

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

Formats the value using the given formatter.

impl FromCursor for RowsMetadata

fn from_cursor( cursor: &mut Cursor<&[u8]>, version: Version ) -> Result<RowsMetadata>

Tries to parse Self from a cursor of bytes.

impl Hash for RowsMetadata

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RowsMetadata

fn eq(&self, other: &RowsMetadata) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RowsMetadata

fn serialize(&self, cursor: &mut Cursor<&mut Vec<u8>>, version: Version)

Serializes given value using the cursor.

fn serialize_to_vec(&self, version: Version) -> Vec<u8>

Wrapper for easily starting hierarchical serialization.
