Enum Cell 

pub enum Cell {
    Null,
    Bool(bool),
    Int(i64),
    Uint(u64),
    Float(f64),
    Text(String),
    Bytes(Vec<u8>),
    Timestamp(DateTime<Utc>),
    Date(NaiveDate),
}

One cell’s value.

Variants

Null

SQL NULL, or a column the driver did not return.

Bool(bool)

A boolean.

Int(i64)

A signed integer.

Uint(u64)

An unsigned integer.

Float(f64)

A floating-point number.

Text(String)

Text.

Bytes(Vec<u8>)

Binary.

Timestamp(DateTime<Utc>)

A UTC timestamp.

Date(NaiveDate)

A calendar date.

Implementations

impl Cell

pub fn as_u64(&self) -> Option<u64>

The cell as an unsigned count, for a COUNT(*) column.

A driver may report the count as signed or unsigned depending on the engine; a negative one is impossible, so it clamps rather than failing.

pub fn to_value(&self) -> Option<Value>

The cell as a bindable Value, for feeding one query’s output into the next — reading a pivot, then the rows it points at.

Null is None: a NULL key links nothing, and binding it would make IN (NULL) match no row while looking like it might.
