Implementations

impl Val

pub fn get_field(&self, key: &str) -> Val

O(1) field lookup — returns a clone of the child (cheap: Arc bump for Arr/Obj, copy for scalars).

pub fn get_index(&self, i: i64) -> Val

O(1) index — returns a clone of the element (cheap: Arc bump for Arr/Obj).

pub fn is_null(&self) -> bool

pub fn is_bool(&self) -> bool

pub fn is_number(&self) -> bool

pub fn is_string(&self) -> bool

pub fn is_array(&self) -> bool

pub fn is_object(&self) -> bool

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

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

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

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

pub fn as_array(&self) -> Option<&[Val]>

pub fn as_array_mut(&mut self) -> Option<&mut Vec<Val>>

pub fn as_object(&self) -> Option<&IndexMap<Arc<str>, Val>>

pub fn as_object_mut(&mut self) -> Option<&mut IndexMap<Arc<str>, Val>>

pub fn get(&self, key: &str) -> Option<&Val>

Read-only get (serde_json compat shim).

pub fn type_name(&self) -> &'static str

pub fn into_vec(self) -> Option<Vec<Val>>

Consume self and produce a mutable Vec (clone only if shared).

pub fn into_map(self) -> Option<IndexMap<Arc<str>, Val>>

Consume self and produce a mutable map (clone only if shared).

pub fn arr(v: Vec<Val>) -> Self

Build a Val::Arr from a Vec without an extra allocation.

pub fn obj(m: IndexMap<Arc<str>, Val>) -> Self

Build a Val::Obj from an IndexMap without an extra allocation.

pub fn key(s: &str) -> Arc<str>

Intern a string key.

Trait Implementations

impl Clone for Val

fn clone(&self) -> Val

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Val

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

Formats the value using the given formatter.

impl Display for Val

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

Formats the value using the given formatter.

impl From<&Value> for Val

fn from(v: &Value) -> Self

Converts to this type from the input type.

impl From<Val> for Value

fn from(v: Val) -> Self

Converts to this type from the input type.

impl Hash for Val

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Val

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
