[−][src]Enum wasm_rpc::ObjectKey
A simplified CBOR value containing only types useful for keys.
Variants
Integer(i64)
An integer.
Bytes(Vec<u8>)
A byte string.
String(String)
An UTF-8 string.
Bool(bool)
A boolean value.
Null
No value.
Methods
impl ObjectKey
[src]
pub fn is_bytes(&self) -> bool
[src]
Returns true if the ObjectKey is a byte string.
pub fn as_bytes(&self) -> Option<&Vec<u8>>
[src]
Returns the associated byte string or None
if the ObjectKey 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 ObjectKey has a different type.
pub fn is_string(&self) -> bool
[src]
Returns true if the ObjectKey is a string.
pub fn as_string(&self) -> Option<&String>
[src]
Returns the associated string or None
if the *ObjectKey` has a different type.
pub fn as_string_mut(&mut self) -> Option<&mut String>
[src]
Returns the associated mutable string or None
if the ObjectKey
has a different type.
pub fn is_number(&self) -> bool
[src]
Retrns true if the ObjectKey
is a number.
pub fn as_i64(&self) -> Option<i64>
[src]
If the ObjectKey
is a number, return or cast it to a i64. Returns None otherwise.
pub fn as_u64(&self) -> Option<u64>
[src]
If the ObjectKey
is a number, return or cast it to a u64. Returns None otherwise.
pub fn is_boolean(&self) -> bool
[src]
Returns true if the ObjectKey is a boolean.
pub fn as_boolean(&self) -> Option<bool>
[src]
If the ObjectKey is a Boolean, returns the associated bool. Returns None otherwise.
pub fn is_null(&self) -> bool
[src]
Returns true if the ObjectKey is a Null. Returns false otherwise.
pub fn as_null(&self) -> Option<()>
[src]
If the ObjectKey is a Null, returns (). Returns None otherwise.
