Enum InstructionModifier 

pub enum InstructionModifier {
    StateAppend(Vec<String>),
    CustomAppend(Arc<dyn Fn(&State) -> String + Send + Sync>),
    Conditional {
        predicate: Arc<dyn Fn(&State) -> bool + Send + Sync>,
        text: String,
    },
}

A modifier that transforms a phase instruction based on runtime state.

Modifiers are evaluated in order during instruction composition. They compose additively — each appends to the instruction built so far.

Variants

StateAppend(Vec<String>)

Append formatted state values: [Context: key1=val1, key2=val2, ...]

CustomAppend(Arc<dyn Fn(&State) -> String + Send + Sync>)

Append the result of a custom formatter function.

Conditional

Conditionally append text when a predicate is true.

Fields

predicate: Arc<dyn Fn(&State) -> bool + Send + Sync>

Predicate that determines whether to append the text.

text: String

Text to append when the predicate is true.

Implementations

impl InstructionModifier

pub fn apply(&self, base: &mut String, state: &State)

Apply this modifier to a base instruction string, mutating it in place.

Trait Implementations

impl Clone for InstructionModifier

fn clone(&self) -> InstructionModifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.
