Implementations§

impl FunctionCode

pub const fn new(value: u8) -> Self

Create a new FunctionCode with value.

pub const fn value(self) -> u8

Gets the u8 value of the current FunctionCode.

Trait Implementations§

impl Clone for FunctionCode

fn clone(&self) -> FunctionCode

Returns a duplicate of the value. Read more

1.0.0 (const: unstable) · Source§

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

Performs copy-assignment from source. Read more

impl Copy for FunctionCode

impl Debug for FunctionCode

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

Formats the value using the given formatter. Read more

impl Display for FunctionCode

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

Formats the value using the given formatter. Read more

impl Eq for FunctionCode

impl PartialEq for FunctionCode

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

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

1.0.0 (const: unstable) · Source§

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

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