pub fn as_null(&self) -> Option<()>

If the Value is a Null, returns (). Returns None otherwise.

pub fn as_number(&self) -> Option<&Number>

If the Value is a Number, returns the associated Number. Returns None otherwise.

If the Value is a String, returns the associated str. Returns None otherwise.

pub fn as_u64(&self) -> Option<u64>

If the Value is a Number, represent it as u64 if possible. Returns None otherwise.

pub fn is_array(&self) -> bool

Returns true if the Value is an Array. Returns false otherwise.

For any Value on which is_array returns true, as_array and as_array_mut are guaranteed to return the vector representing the array.

pub fn is_boolean(&self) -> bool

Returns true if the Value is a Boolean. Returns false otherwise.

For any Value on which is_boolean returns true, as_bool is guaranteed to return the boolean value.

pub fn is_f64(&self) -> bool

Returns true if the Value is a number that can be represented by f64.

For any Value on which is_f64 returns true, as_f64 is guaranteed to return the floating point value.

pub fn is_i64(&self) -> bool

Returns true if the Value is an integer between i64::MIN and i64::MAX.

For any Value on which is_i64 returns true, as_i64 is guaranteed to return the integer value.

pub fn is_number(&self) -> bool

Returns true if the Value is a Number. Returns false otherwise.

pub fn is_null(&self) -> bool

Returns true if the Value is a Null. Returns false otherwise.

For any Value on which is_null returns true, as_null is guaranteed to return Some(()).

pub fn is_object(&self) -> bool

Returns true if the Value is an Object. Returns false otherwise.

For any Value on which is_object returns true, as_object and as_object_mut are guaranteed to return the map representation of the object.

pub fn is_string(&self) -> bool

Returns true if the Value is a String. Returns false otherwise.

For any Value on which is_string returns true, as_str is guaranteed to return the string slice.

pub fn is_u64(&self) -> bool

Returns true if the Value is an integer between zero and u64::MAX.

For any Value on which is_u64 returns true, as_u64 is guaranteed to return the integer value.

pub fn take(&mut self) -> Value

Takes the value out of the Value, leaving a Null in its place.
