Enum ValueRef 

pub enum ValueRef<'a> {
    Null,
    Bool(bool),
    Int(i64),
    Float(f64),
    Str(&'a str),
    List(&'a [ValueRef<'a>]),
    Map(MapRef<'a>),
    Ref {
        kind: KindName,
        id: &'a str,
    },
    Bytes(&'a [u8]),
}

A borrowed Value: the same cases, strings &'a str, lists and maps slices.

Variants

Null

Nothing.

Bool(bool)

true or false.

Int(i64)

An integer.

Float(f64)

A number with a fraction or an exponent.

Str(&'a str)

A string, as spelled.

List(&'a [ValueRef<'a>])

A list, in the arena.

Map(MapRef<'a>)

A map, in the arena.

Ref

@file:images/logo.png: its kind checked, its id as written (checked where it was read).

Fields

kind: KindName

Its kind.

id: &'a str

Its id, as written.

Bytes(&'a [u8])

Bytes as they are.

Implementations

impl<'a> ValueRef<'a>

pub fn kind(&self) -> ValueKind

Which case it is.

pub fn is_null(&self) -> bool

Whether it’s null.

pub fn as_bool(&self) -> Option<bool>

The bool, if it’s one.

pub fn as_i64(&self) -> Option<i64>

The integer, if it’s one (a float with no fraction is).

pub fn as_f64(&self) -> Option<f64>

The number, if it’s one.

pub fn as_str(&self) -> Option<&'a str>

The string, if it’s one.

pub fn as_list(&self) -> Option<&'a [ValueRef<'a>]>

The list, if it’s one.

pub fn as_map(&self) -> Option<MapRef<'a>>

The map, if it’s one.

pub fn get(&self, key: &str) -> Option<&'a ValueRef<'a>>

self[key] of a map, None for anything else.

pub fn to_value(self) -> Value

An owned copy.

pub fn to_ref(self) -> Option<Ref>

The reference of a Ref, owned.
