Struct PluginState 

pub struct PluginState { /* private fields */ }

Per-instance host state shared with the Wasmtime store.

Contains the WASIp1 context, the capability grants, and the shared ring buffer location for the current plugin instance.

Examples

use martensite_plugin::{CapabilitySet, PluginRuntime};

let runtime = PluginRuntime::new().unwrap();
// `PluginState` is created internally during `load` and holds the
// capability set granted to the plugin instance.
let _ = runtime.load(b"\0asm\x01\0\0\0", CapabilitySet::empty());

Implementations

impl PluginState

pub fn capabilities(&self) -> &CapabilitySet

Returns a reference to the capability set for this instance.

Examples

use martensite_plugin::{Capability, CapabilitySet, PluginRuntime};

let wasm_bytes: &[u8] = b"";
let caps = CapabilitySet::builder().grant(Capability::Network).build();
let runtime = PluginRuntime::new().unwrap();
let plugin = runtime.load(wasm_bytes, caps).unwrap();
assert!(plugin.capabilities().contains(&Capability::Network));
