Enum cfx_vm_types::BlockHashSource

pub enum BlockHashSource {
    Env,
    State,
}

Variants

Env

Before CIP-133, block hash is read from Env, same as the Ethereum

State

After CIP-133, block hash is read from State

Trait Implementations

impl Clone for BlockHashSource

fn clone(&self) -> BlockHashSource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockHashSource

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

Formats the value using the given formatter.

impl Hash for BlockHashSource

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

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 BlockHashSource

fn eq(&self, other: &BlockHashSource) -> 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.
