Enum EmbeddedBackend 

pub enum EmbeddedBackend {
    Ast,
    Vm,
}

Which backend a built binary runs its program on.

Fixed at build time like everything else the binary carries, and for the same reason: a flag that chose it would be a flag, and a built binary honours none. cove build --backend ast is where the choice is made.

Variants

Ast

The tree-walking interpreter, which ADR 0034 keeps as the semantic oracle.

Vm

The linear-memory backend of ADR 0034, which is what a run runs on unless the build asked otherwise.

Trait Implementations

impl Clone for EmbeddedBackend

fn clone(&self) -> EmbeddedBackend

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for EmbeddedBackend

impl Debug for EmbeddedBackend

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for EmbeddedBackend

impl PartialEq for EmbeddedBackend

fn eq(&self, other: &EmbeddedBackend) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
