Struct VM 

pub struct VM<'t> { /* private fields */ }

Virtual machine state for query execution.

Implementations

impl<'t> VM<'t>

pub fn builder(source: &'t str, tree: &'t Tree) -> VMBuilder<'t>

Create a VM builder.

pub fn new( source: &'t str, tree: &'t Tree, trivia_types: Vec<u16>, limits: FuelLimits, ) -> VM<'t>

👎Deprecated: Use VM::builder(source, tree).trivia_types(…).build() instead

Create a new VM for execution.

pub fn execute( self, module: &Module, bootstrap: u16, entrypoint: &Entrypoint, ) -> Result<EffectLog<'t>, RuntimeError>

Execute query from entrypoint, returning effect log.

This is a convenience method that uses NoopTracer, which gets completely optimized away at compile time.

pub fn execute_with<T>( self, module: &Module, bootstrap: u16, entrypoint: &Entrypoint, tracer: &mut T, ) -> Result<EffectLog<'t>, RuntimeError>

where T: Tracer,

Execute query with a tracer for debugging.

The tracer is generic, so NoopTracer calls are optimized away while PrintTracer calls collect execution trace.

bootstrap is the preamble entry point - caller decides which preamble to use.
