Struct viceroy_lib::ExecuteCtx [−][src]
pub struct ExecuteCtx { /* fields omitted */ }Expand description
Execution context used by a ViceroyService.
This is all of the state needed to instantiate a module, in order to respond to an HTTP
request. Note that it is very important that ExecuteCtx be cheaply clonable, as it is cloned
every time that a viceroy service handles an incoming connection.
Implementations
Create a new execution context, given the path to a module.
Set the backends for this execution context.
Get the dictionaries for this execution context.
Set the dictionaries for this execution context.
Set the path to the config for this execution context.
Whether to treat stdout as a logging endpoint.
Set the stdout logging policy for this execution context.
Whether to treat stderr as a logging endpoint.
Set the stderr logging policy for this execution context.
Gets the TLS configuration
Asynchronously handle a request.
This method fully instantiates the wasm module housed within the ExecuteCtx,
including running the wasm start function. It then proceeds to execute the
instantiated module’s WASI entry point, running to completion. If execution
results in an error, a response is still produced, but with a 500 status code.
Build time: Before you build or test your code, we recommend to set the release flag
e.g. cargo test --release otherwise the execution will be very slow. This has to do
with the Cranelift compiler, which is extremely slow when compiled in debug mode.
Example
let ctx = ExecuteCtx::new("path/to/a/file.wasm")?;
let resp = ctx.handle_request(req, "127.0.0.1".parse().unwrap()).await?;Trait Implementations
