Implementations

impl Value

pub fn is_nil(&self) -> bool

Returns true if the Value is nil.

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

If the Value is boolean, returns contained value.

pub fn as_bin(&self) -> Option<&[u8]>

If the Value is bin, returns contained slice.

pub fn as_extension(&self) -> Option<(i8, &[u8])>

If the Value is ext, returns (type, data) as tuple.

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

If the Value is number, returns contained value.

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

If the Value is str, returns contained slice.

pub fn as_array(&self) -> Option<&[Value]>

If the Value is array, returns contained slice.

pub fn as_map(&self) -> Option<&[(Value, Value)]>

If the Value is map, returns contained slice of pairs.
