Methods

impl ObjectKey

pub fn is_bytes(&self) -> bool

Returns true if the ObjectKey is a byte string.

pub fn as_bytes(&self) -> Option<&Vec<u8>>

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>>

Returns the associated mutable byte string or None if the ObjectKey has a different type.

pub fn is_string(&self) -> bool

Returns true if the ObjectKey is a string.

pub fn as_string(&self) -> Option<&String>

Returns the associated string or None if the *ObjectKey` has a different type.

pub fn as_string_mut(&mut self) -> Option<&mut String>

Returns the associated mutable string or None if the ObjectKey has a different type.

pub fn is_number(&self) -> bool

Retrns true if the ObjectKey is a number.

pub fn as_i64(&self) -> Option<i64>

If the ObjectKey is a number, return or cast it to a i64. Returns None otherwise.

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

If the ObjectKey is a number, return or cast it to a u64. Returns None otherwise.

pub fn is_boolean(&self) -> bool

Returns true if the ObjectKey is a boolean.

pub fn as_boolean(&self) -> Option<bool>

If the ObjectKey is a Boolean, returns the associated bool. Returns None otherwise.

pub fn is_null(&self) -> bool

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

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

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