Enum ContextFrame 

pub enum ContextFrame {
    Indexed {
        data: Value,
        index: usize,
    },
    Keyed {
        data: Value,
        index: usize,
        key: String,
    },
    Reduce {
        current: Value,
        accumulator: Value,
    },
    Data(Value),
}

A single frame in the context stack, optimized as an enum to minimize size.

Field usage analysis shows mutually exclusive patterns:

• 59% of frames use only data + index (array iteration)
• 18% use data + index + key (object iteration)
• 9% use reduce_current + reduce_accumulator (reduce operations)
• 14% use only data (error context, etc.)

Variants

Indexed

Array iteration frame — most common (data + index)

Fields

data: Value

index: usize

Keyed

Object iteration frame (data + index + key)

Fields

data: Value

index: usize

key: String

Reduce

Reduce operation frame (current + accumulator)

Fields

current: Value

accumulator: Value

Data(Value)

Simple data-only frame

Implementations

impl ContextFrame

pub fn data(&self) -> &Value

Get the data value for this frame

pub fn get_index(&self) -> Option<usize>

Get the index if available

pub fn get_key(&self) -> Option<&str>

Get the key if available

pub fn get_reduce_current(&self) -> Option<&Value>

Get the reduce “current” value if this is a reduce frame

pub fn get_reduce_accumulator(&self) -> Option<&Value>

Get the reduce “accumulator” value if this is a reduce frame
