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,

Feeds a slice of this type into the given Hasher.

impl Ord for RowsMetadata

fn cmp(&self, other: &RowsMetadata) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<RowsMetadata> 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 PartialOrd<RowsMetadata> for RowsMetadata

fn partial_cmp(&self, other: &RowsMetadata) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

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.

impl Eq for RowsMetadata

impl StructuralEq for RowsMetadata
