Methods
impl Value
[src]
pub fn is_object(&self) -> bool
[src]
Returns true if the value is an object.
pub fn as_object(&self) -> Option<&BTreeMap<ObjectKey, Value>>
[src]
If the value is an object, returns the associated BTreeMap. Returns None otherwise.
pub fn as_object_mut(&mut self) -> Option<&mut BTreeMap<ObjectKey, Value>>
[src]
If the value is an object, returns the associated mutable BTreeMap. Returns None otherwise.
pub fn is_array(&self) -> bool
[src]
Returns true if the value is an array.
pub fn as_array(&self) -> Option<&Vec<Value>>
[src]
If the value is an array, returns the associated Vec. Returns None otherwise.
pub fn as_array_mut(&mut self) -> Option<&mut Vec<Value>>
[src]
If the value is an array, returns the associated mutable Vec. Returns None otherwise.
pub fn is_bytes(&self) -> bool
[src]
Returns true if the value is a byte string.
pub fn as_bytes(&self) -> Option<&Vec<u8>>
[src]
Returns the associated byte string or None
if the value has a different type.
pub fn as_bytes_mut(&mut self) -> Option<&mut Vec<u8>>
[src]
Returns the associated mutable byte string or None
if the value has a different type.
pub fn is_string(&self) -> bool
[src]
Returns true if the value is a string.
pub fn as_string(&self) -> Option<&String>
[src]
Returns the associated string or None
if the value has a different type.
pub fn as_string_mut(&mut self) -> Option<&mut String>
[src]
Returns the associated mutable string or None
if the value has a different type.
pub fn is_number(&self) -> bool
[src]
Retrns true if the value is a number.
pub fn is_i64(&self) -> bool
[src]
Returns true if the Value
is a i64. Returns false otherwise.
pub fn is_u64(&self) -> bool
[src]
Returns true if the Value
is a u64. Returns false otherwise.
pub fn is_f64(&self) -> bool
[src]
Returns true if the Value
is a f64. Returns false otherwise.
pub fn as_i64(&self) -> Option<i64>
[src]
If the Value
is a number, return or cast it to a i64. Returns None otherwise.
pub fn as_u64(&self) -> Option<u64>
[src]
If the Value
is a number, return or cast it to a u64. Returns None otherwise.
pub fn as_f64(&self) -> Option<f64>
[src]
If the Value
is a number, return or cast it to a f64. Returns None otherwise.
pub fn is_boolean(&self) -> bool
[src]
Returns true if the value is a boolean.
pub fn as_boolean(&self) -> Option<bool>
[src]
If the value is a Boolean, returns the associated bool. Returns None otherwise.
pub fn is_null(&self) -> bool
[src]
Returns true if the value is a Null. Returns false otherwise.
pub fn as_null(&self) -> Option<()>
[src]
If the value is a Null, returns (). Returns None otherwise.
