Implementations

impl DeserializedMetadataAndRawRows

pub fn metadata(&self) -> &ResultMetadata<'_>

Returns the metadata associated with this response (table and column specifications).

pub fn into_metadata(self) -> ResultMetadataHolder

Consumes the DeserializedMetadataAndRawRows and returns metadata associated with the response (or cached metadata, if used in its stead).

pub fn rows_count(&self) -> usize

Returns the number of rows that the RESULT:Rows contain.

pub fn rows_bytes_size(&self) -> usize

Returns the serialized size of the raw rows.

pub fn mock_empty() -> Self

pub fn rows_iter<'frame, 'metadata, R: DeserializeRow<'frame, 'metadata>>( &'frame self, ) -> StdResult<TypedRowIterator<'frame, 'metadata, R>, TypeCheckError>

where 'frame: 'metadata,

Creates a typed iterator over the rows that lazily deserializes rows in the result.

Returns Err if the schema of returned result doesn’t match R.
