Enum CallInput 

pub enum CallInput {
    SharedBuffer(Range<usize>),
    Bytes(Bytes),
}

Input enum for a call.

As CallInput uses shared memory buffer it can get overridden if not used directly when call happens.

Variants

SharedBuffer(Range<usize>)

The Range points to the SharedMemory buffer. Buffer can be found in context_interface::LocalContextTr::shared_memory_buffer_slice function. And can be accessed with evm.ctx().local().shared_memory_buffer()

Warning

Use it with caution, CallInput shared buffer can be overridden if context from child call is returned so recommendation is to fetch buffer at first Inspector call and clone it from context_interface::LocalContextTr::shared_memory_buffer_slice function.

Bytes(Bytes)

Bytes of the call data.

Implementations

impl CallInput

pub fn len(&self) -> usize

Returns the length of the call input.

pub fn is_empty(&self) -> bool

Returns true if the call input is empty.

pub fn bytes<CTX>(&self, ctx: &CTX) -> Bytes

where CTX: ContextTr,

Returns the bytes of the call input.

SharedMemory buffer can be shrunked or overwritten if the child call returns the shared memory context to its parent, the range in CallInput::SharedBuffer can show unexpected data.

Allocation

If this CallInput is a SharedBuffer, the slice will be copied into a fresh Bytes buffer, which can pose a performance penalty.

Trait Implementations

impl Clone for CallInput

fn clone(&self) -> CallInput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallInput

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

Formats the value using the given formatter.

impl Default for CallInput

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CallInput

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CallInput

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

impl Serialize for CallInput

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CallInput
