Struct light_snowflake_connector::Partition

pub struct Partition { /* private fields */ }

A single in-memory chunk of a query response

Most partitions are in the single digits of megabytes, so clones are not too expensive, but still should be avoided if possible.

The data returned from Snowflake is a list of lists of strings, so there are many type conversions involved, see Cell for more

Implementations

impl Partition

pub fn index(&self) -> usize

Get the index of this partition

pub fn num_rows(&self) -> usize

Get the number of rows in just this partition This is obtained from data.len() rather than the metadata because this partition may have been constructed by concatenating

pub fn raw_cells(&self) -> &[Vec<Option<String>>]

Get the cells in this partition as strings just as they were returned from Snowflake

This could be more efficient for some use cases than converting to Cells but without the type information it could be difficult to work with

pub fn cells(&self) -> Vec<Vec<Cell>>

Convert the response into Cells in a list of lists format

This most closely matches the format of the response from Snowflake

pub fn json_table(&self) -> Vec<Vec<Value>>

Convert the response into serde_json::Values in a list of lists format

pub fn json_objects(&self) -> Vec<Value>

Convert the response into serde_json::Values in a list of objects format
