Struct holochain_core::nucleus::ribosome::Runtime

pub struct Runtime {
    pub memory_manager: SinglePageManager,
    pub context: Arc<Context>,
    pub dna_name: String,
    pub zome_call: ZomeFnCall,
}

Object holding data to pass around to invoked Zome API functions

Fields

memory_manager: SinglePageManager

Memory state tracker between ribosome and wasm.

context: Arc<Context>

Context of Holochain. Required for operating.

dna_name: String

Name of the DNA that is being hosted.

zome_call: ZomeFnCall

The zome function call that initiated the Ribosome.

Methods

impl Runtime

pub fn load_utf8_from_args(&self, args: &RuntimeArgs) -> String

Load a string stored in wasm memory. Input RuntimeArgs should only have one input which is the encoded allocation holding the complex data as an utf8 string. Returns the utf8 string.

pub fn store_utf8(     &mut self,     json_str: &str ) -> Result<Option<RuntimeValue>, Trap>

Store a string in wasm memory. Input should be a a json string. Returns a Result suitable to return directly from a zome API function, i.e. an encoded allocation

Trait Implementations

impl Clone for Runtime

fn clone(&self) -> Runtime

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Externals for Runtime

fn invoke_index(     &mut self,     index: usize,     args: RuntimeArgs ) -> Result<Option<RuntimeValue>, Trap>

Perform invoke of a host function by specified index.
