Struct gluon_vm::vm::VmEnv

pub struct VmEnv {
    pub type_infos: TypeInfos,
    pub globals: FnvMap<StdString, Global>,
}

A borrowed structure which implements CompilerEnv, TypeEnv and KindEnv allowing the typechecker and compiler to lookup things in the virtual machine.

Fields

type_infos: TypeInfos

globals: FnvMap<StdString, Global>

Methods

impl VmEnv

pub fn find_type_info(&self, name: &str) -> Result<Cow<Alias<Symbol, ArcType>>>

pub fn get_binding(&self, name: &str) -> Result<(Value, Cow<ArcType>)>

pub fn get_metadata(&self, name_str: &str) -> Result<&Metadata>
