Enum SymbolicWidth 

pub enum SymbolicWidth {
    Fixed(usize),
    SameAs(TableId),
}

A width resolved before decoding, which may still name an operand.

Variants

Fixed(usize)

A concrete width in bytes.

SameAs(TableId)

The width of the value a sub-table operand exports.

Trait Implementations

impl Clone for SymbolicWidth

fn clone(&self) -> SymbolicWidth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SymbolicWidth

impl Debug for SymbolicWidth

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SymbolicWidth

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SymbolicWidth

impl PartialEq for SymbolicWidth

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for SymbolicWidth

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for SymbolicWidth

impl Width for SymbolicWidth

fn fixed(size: usize) -> Self

A concrete width in bytes.

fn size(self) -> Option<usize>

This width as a byte count, if it is concrete. Arithmetic on a width uses this, so a symbolic width yields no constraint rather than a wrong one.

fn operand(table: TableId) -> Option<Self>

The width of the value a sub-table operand exports, if this domain can name it. Concrete domains cannot, and report the width as unknown.
