Enum Phase 

pub enum Phase {
    Read,
    Expand,
    Compile,
    Eval,
}

A stage in the pipeline at which macro expansion may run.

Eval policies consult the phase via EvalPolicy::allow_macro_expansion, and expanders receive it in MacroExpander::expand_expr.

Variants

Read

While reading source forms into expressions.

Expand

During the dedicated macro-expansion pass.

Compile

While compiling expanded expressions.

Eval

During evaluation itself.

Trait Implementations

impl Clone for Phase

fn clone(&self) -> Phase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Phase

impl Debug for Phase

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

Formats the value using the given formatter.

impl Eq for Phase

impl PartialEq for Phase

fn eq(&self, other: &Phase) -> 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.
