Cell types, used for receiving data from Snowflake.

Snowflake returns these as a list of Strings; these are the result of parsing those strings, and as such there are some caveats to be aware of.

Variants

Null

A NULL value. Any column could be null unless it is declared as NOT NULL, but the driver is not aware of this information from the metadata.

Int(i128)

A 128-bit signed integer, 38 digits of precision. Any NUMBER cell that can be represented as an integer will be, but this means that NUMBER columns can contain mixed types: Int and Float.

e.g. ["1", "1.0", "1.1"] will be parsed as [Int(1), Int(1), Float(1.1)]

Float(f64)

A 64-bit floating point number, 15 digits of precision. Any NUMBER cell that cannot be represented as an integer will be parsed as a float. Additionally, all REAL columns will be parsed as floats. This is lossy, but intended for convenience.

Varchar(String)

A variable length string. It must be valid UTF-8.

Binary(Vec<u8>)

A variable length binary string. (This is serialized over the wire as a hex string, so these are not bandwidth efficient.)

Boolean(bool)

A boolean value.

Date(NaiveDate)

A date without a time zone.

Time(NaiveTime)

A time without a time zone.

TimestampLtz(DateTime<Local>)

A timestamp with the local time zone. (This is not extensively tested)

TimestampNtz(NaiveDateTime)

A timestamp without a time zone. Presumably this is UTC, but it is not specified.

Trait Implementations

impl Clone for Cell

fn clone(&self) -> Cell

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

Performs copy-assignment from source.

impl Debug for Cell

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

Formats the value using the given formatter.

impl From<Cell> for Value

fn from(cell: Cell) -> Self

Converts to this type from the input type.
