Struct fr::ir::Value

pub struct Value {
    pub offset: u32,
    pub reference_depth: u32,
    pub number_cells: u32,
}

This object represents a value stored on the tape. Objects can be stored indirectly or directly. In brainfuck compatibility mode, dereferencing or referencing an object is illegal.

Fields

offset: u32

reference_depth: u32

number_cells: u32

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Value

impl Debug for Value

This is for debugging.

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

impl Eq for Value

impl Lower for Value

A value can be lowered into a value

fn lower(&self) -> Result<Value, Error>

impl PartialEq<Value> for Value

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<Value> for Value

fn partial_cmp(&self, other: &Value) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Value) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Value) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Value) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Value) -> bool
