Struct evm::Valids

pub struct Valids(/* private fields */);

Mapping of valid jump destination from code.

Implementations

impl Valids

pub fn new(code: &[u8]) -> Valids

Create a new valid mapping from given code bytes.

pub fn len(&self) -> usize

Get the length of the valid mapping. This is the same as the code bytes.

pub fn is_empty(&self) -> bool

Returns true if the valids list is empty

pub fn is_valid(&self, position: usize) -> bool

Returns true if the position is a valid jump destination. If not, returns false.

Trait Implementations

impl Clone for Valids

fn clone(&self) -> Valids

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Valids

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

Formats the value using the given formatter.

impl PartialEq for Valids

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

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

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

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