Enum serde_utils::Obj

pub enum Obj {
    Null,
    Bool(bool),
    Signed(i64),
    Unsigned(u64),
    Float(f64),
    Str(String),
    Bin(ByteBuf),
    List(Vec<Obj>),
    Map(BTreeMap<Obj, Obj>),
}

A generic object that can hold any value deserialized via Serde.

The important aspect of this generic object enum is that it can consume all possible values and does not expect any specific types. This makes it possible to deserialize data first and interpret it later.

Warning: Deserializing and even serializing unknown content allows attackers to control the recursion depth of the process and potentially crash it (although in a safe way).

Note: The implementations of PartialEq, PartialOrd, and Ord traits treat NAN floats as equal. The implementations of Hash, PartialEq, PartialOrd, and Ord traits treat non-negative Signed objects like Unsigned objects with the same value.

Trait Implementations

impl Debug for Obj

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for Obj

fn clone(&self) -> Obj

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Obj

fn default() -> Obj

Returns the "default value" for a type.

impl PartialEq for Obj

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Eq for Obj

impl PartialOrd for Obj

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Ord for Obj

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

impl Hash for Obj

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

Feeds this value into the state given, updating the hasher as necessary.

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

Feeds a slice of this type into the state provided.

impl Serialize for Obj

fn serialize<S: Serializer>(&self, ser: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl<'a> Deserialize<'a> for Obj

fn deserialize<D: Deserializer<'a>>(de: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for Obj

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

Formats the value using the given formatter.
