Enum MethodContext

#[repr(u8)]
pub enum MethodContext {
    Keep = 0,
    Reset = 1,
    Replace = 2,
}

Context for method call.

Initially, context is Address::NULL. For each call into another contract, the context of the current method can be either preserved, reset to Address::NULL or replaced with the current contract’s address.

Variants

Keep = 0

Keep current context

Reset = 1

Reset context to Address::NULL

Replace = 2

Replace context with current contract’s address

Trait Implementations

impl Clone for MethodContext

fn clone(&self) -> MethodContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MethodContext

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

Formats the value using the given formatter.

impl PartialEq for MethodContext

fn eq(&self, other: &MethodContext) -> 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 TrivialType for MethodContext

const METADATA: &[u8]

Data structure metadata in binary form, describing shape and types of the contents, see IoTypeMetadataKind for encoding details.

const SIZE: u32 = _

unsafe fn from_bytes(bytes: &[u8]) -> Option<&Self>

Create a reference to a type, which is represented by provided memory.

unsafe fn from_bytes_mut(bytes: &mut [u8]) -> Option<&mut Self>

Create a mutable reference to a type, which is represented by provided memory.

fn as_bytes(&self) -> &[u8]

Access underlying byte representation of a data structure

unsafe fn as_bytes_mut(&mut self) -> &mut [u8]

Access underlying mutable byte representation of a data structure.
