[−][src]Enum sp_core::ExecutionContext

pub enum ExecutionContext {
    Importing,
    Syncing,
    BlockConstruction,
    OffchainCall(Option<(Box<dyn Externalities>, Capabilities)>),
}

Context for executing a call into the runtime.

Variants

Importing

Context for general importing (including own blocks).

Syncing

Context used when syncing the blockchain.

BlockConstruction

Context used for block construction.

OffchainCall(Option<(Box<dyn Externalities>, Capabilities)>)

Context used for offchain calls.

This allows passing offchain extension and customizing available capabilities.

Implementations

impl ExecutionContext[src]

pub fn capabilities(&self) -> Capabilities[src]
