Enum ValueTag 

#[repr(u8)]
pub enum ValueTag {
    Null = 0,
    False = 1,
    True = 3,
    Int = 4,
    Float = 5,
    Text = 6,
    Container = 7,
}

What the low three bits of a value header say the value is.

The numbers are the format, so they are written out rather than derived from declaration order, and 2 is missing on purpose: false and true are 1 and 3 so that the low bit of a boolean is the boolean.

Variants

Null = 0

null.

False = 1

false.

True = 3

true.

Int = 4

A signed integer, stored in one, two, four or eight bytes.

Float = 5

A 64 bit float.

Text = 6

A UTF-8 string.

Container = 7

An object or an array, told apart by doc_flags::ARRAY.

Implementations

impl ValueTag

pub const fn as_u8(self) -> u8

The byte that stands for this tag.

pub const fn from_u8(b: u8) -> Option<ValueTag>

The tag for a byte, or None for the one value in the range this version does not define.

pub const fn is_container(self) -> bool

Whether this tag is a container rather than a scalar.
