Struct GXHandle

pub struct GXHandle(/* private fields */);

Expand description

A handle to a running GX instance. Drop the handle to shutdown the associated background tasks.

Implementations§

impl GXHandle

pub async fn get_env(&self) -> Result<Env<GXCtx, NoUserEvent>>

Get a copy of the current graphix environment

pub async fn compile(&self, text: ArcStr) -> Result<CompRes>

Compile and execute the specified graphix expression. If it generates results, they will be sent to all the channels that are subscribed. When the CompExp objects contained in the CompRes are dropped their corresponding expressions will be deleted. Therefore, you can stop execution of the whole expression by dropping the returned CompRes.

pub async fn load(&self, path: PathBuf) -> Result<CompRes>

Load and execute the specified graphix module. The path may have one of two forms. If it is the path to a file with extension .bs then the rt will load the file directly. If it is a modpath (e.g. foo::bar::baz) then the module resolver will look for a matching module in the modpath. When the CompExp objects contained in the CompRes are dropped their corresponding expressions will be deleted. Therefore, you can stop execution of the whole file by dropping the returned CompRes.

pub async fn compile_callable(&self, id: Value) -> Result<Callable>

Compile a callable interface to the specified lambda id. This is how you call a lambda directly from rust. When the returned Callable is dropped the associated callsite will be delete.

pub async fn compile_ref(&self, id: impl Into<BindId>) -> Result<Ref>

Compile an expression that will output the value of the ref specifed by id. This is the same as the deref (*) operator in graphix. When the returned Ref is dropped the compiled code will be deleted.

pub fn set<T: Into<Value>>(&self, id: BindId, v: T) -> Result<()>

Set the variable idenfified by id to v, triggering updates of all dependent node trees.
