Enum dust_lib::Value

pub enum Value {
    String(String),

Whale value representation.

Every whale variable has a key and a Value. Variables are represented by storing them in a VariableMap. This means the map of variables is itself a value that can be treated as any other.

Float(f64)

Integer(i64)

Boolean(bool)

List(Vec<Value>)

pub fn as_fixed_len_list(&self, len: usize) -> Result<&Vec<Value>>

Borrows the value stored in self as Vec<Value> or returns Err if self is not a Value::Map of the required length.

pub fn as_map(&self) -> Result<&VariableMap>

Borrows the value stored in self as Vec<Value>, or returns Err if self is not a Value::Map.

pub fn as_table(&self) -> Result<&Table>

Borrows the value stored in self as Vec<Value>, or returns Err if self is not a Value::Table.

pub fn as_function(&self) -> Result<&Function>

Borrows the value stored in self as Function, or returns Err if self is not a Value::Function.

pub fn as_time(&self) -> Result<&Time>

pub fn as_empty(&self) -> Result<()>

Returns (), or returnsErr if self is not a Value::Tuple.

pub fn to_table(&self) -> Result<Table>

Returns an owned table, either by cloning or converting the inner value..
