Implementations

impl VariableType

pub fn size(&self) -> usize

pub fn set_source(self, source: Module<()>) -> Self

pub fn get_source(&self) -> Option<Module<()>>

pub fn convert_to( &self, to_convert_to: &Self, ) -> Result<Self, VariableConversionError>

Try to convert this variable type to another. If the conversion is successful, it returns the new variable type. If it is not successful, it returns Err(VariableConversionError).

Note the rules: - unknown can be converted to anything - nothing can be converted to unknown (except unknown itself) - everything can be converted to any - any can not be converted to anything else - every basic type can be converted to itself

Trait Implementations

impl Clone for VariableType

fn clone(&self) -> VariableType

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VariableType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for VariableType

fn default() -> VariableType

Returns the “default value” for a type.

impl Display for VariableType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for VariableType

type Err = VariableParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for VariableType

fn eq(&self, other: &VariableType) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
