Enum MethodContext 

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

Context for method call.

The correct mental model for context is “user of the child process,” where “process” is a method call. Essentially, something executed with a context of a contract can be thought as done “on behalf” of that contract, which depending on circumstances may or may not be desired.

Initially, the 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. Those are the only options. Contracts do not have privileges to change context to the address of an arbitrary contract.

Variants

Keep = 0

Keep current context

Reset = 1

Reset context to [Address::NULL]

Replace = 2

Replace context with the current contract’s address

Parse the beginning of aligned bytes, returns the value and the remaining bytes.

final fn try_from_bytes_exact(bytes: &[u8]) -> Option<&Self>

Like [Self::try_from_bytes()], but returns None if there are more bytes than the value

final fn try_from_bytes_mut(bytes: &mut [u8]) -> Option<(&mut Self, &mut [u8])>

Like [Self::try_from_bytes()], but returns an exclusive reference.
