Methods

impl Obj

fn new() -> Obj

fn is_empty(&self) -> bool

Returns whether this Obj is empty.

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

Returns whether this Arr and other point to the same data.

fn contains(&self, field: &str) -> bool

Returns true iff the Obj contains field.

fn remove(&mut self, field: &str) -> Option<Value>

Removes a field and its associated value from the Obj.

fn clear(&mut self)

Clears all fields from the Obj.

fn get(&self, field: &str) -> Option<Value>

Gets the Value associated with field.

fn get_bool(&self, field: &str) -> OverResult<bool>

Try to get the $type associated with field.

fn get_int(&self, field: &str) -> OverResult<BigInt>

Trait Implementations

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 Debug for Obj

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

Formats the value using the given formatter.

impl Default for Obj

fn default() -> Self

Returns the "default value" for a type.

impl FromStr for Obj

type Err = OverError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this 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 PartialEq<Value> for Obj

fn eq(&self, other: &Value) -> 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 !=.
