Enum Cell 

pub enum Cell {
    Null,
    Bool(bool),
    Number {
        value: f64,
        lexeme: Option<Box<str>>,
    },
    String(Box<str>),
    Missing,
}

One projected value.

Variants

Null

Bool(bool)

Number

Fields

value: f64

lexeme: Option<Box<str>>

String(Box<str>)

Missing

The source had no value at the column’s path. Not null, not the empty string, not zero: a policy maps or rejects it later.

Implementations

impl Cell

pub fn from_datum(d: &Datum) -> Cell

From a retained value. A container is not a cell; it is serialized as compact JSON text, which is the lossy but unambiguous choice the standard binding makes and documents.

pub fn from_owned(d: Datum) -> Cell

Cell::from_datum for a value the caller owns: the text moves instead of being copied.

pub fn is_missing(&self) -> bool

pub fn byte_size(&self) -> usize

The bytes this cell retains, on the same basis as Datum::byte_size.

Trait Implementations

impl Clone for Cell

fn clone(&self) -> Self

Returns a duplicate of the value.

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 Display for Cell

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

The cell as JSON text; Missing prints as missing.

impl PartialEq for Cell

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.
