Enum Computed 

pub enum Computed<'d> {
    Value(Value<'d>),
    Name(&'d [u8]),
    Int(i64),
    Float(f64),
}

One value a projection worked out.

A projection answers numbers and key names rather than places in a document, which is why it is not a Value. The two number kinds are apart because the reference writes $.a + $.b as 7 and $.list.sum() as 7.0, and a client reading the reply back as JSON sees the difference.

Variants

Value(Value<'d>)

A value the document holds.

Name(&'d [u8])

A key name, which is what ~ answers.

Int(i64)

A whole number.

Float(f64)

A number that is not whole.

Implementations

impl Computed<'_>

pub fn write_json_at( &self, f: &Format<'_>, out: &mut Vec<u8>, depth: usize, ) -> Result<()>

This as JSON text, appended to out, as if it sat depth levels inside whatever the caller has already opened.

Errors

A document that arrived damaged, and a number that is not finite, which JSON has no way to write.

Trait Implementations

impl<'d> Clone for Computed<'d>

fn clone(&self) -> Computed<'d>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'d> Copy for Computed<'d>

impl<'d> Debug for Computed<'d>

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

Formats the value using the given formatter.
