fn from_str(s: &str) -> Result<Opcode, &'static str>

Parse an Opcode name from a string.

type Err = &'static str

The associated error which can be returned from parsing.

impl Hash for Opcode

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Opcode

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

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

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

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