Enum JsonProjectionMode 

pub enum JsonProjectionMode {
    TaggedCanonical,
    UntaggedInterop,
    TextLossy,
}

Selects which Expr <-> JSON projection to apply.

Variants

TaggedCanonical

The canonical, lossless projection: $expr-tagged forms that round-trip every Expr exactly. Delegates to crate::expr_to_json / crate::json_to_expr.

UntaggedInterop

A lossy interop projection that emits/accepts plain, untagged JSON.

This is intended for foreign surfaces (for example LLM tool schemas and tool-call arguments) that expect ordinary JSON without kernel tags. It is NOT the canonical codec: structure such as symbols vs strings, number domains, vectors vs lists, and most non-collection forms is collapsed and cannot be recovered. Use JsonProjectionMode::TaggedCanonical whenever faithful round-tripping is required.

TextLossy

A one-way, lossy text projection: Expr -> JSON produces a JSON string containing the debug rendering of the expression. There is no faithful inverse; JSON -> Expr reuses the JsonProjectionMode::UntaggedInterop decoder.

Trait Implementations

impl Clone for JsonProjectionMode

fn clone(&self) -> JsonProjectionMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for JsonProjectionMode

impl Debug for JsonProjectionMode

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

Formats the value using the given formatter.

impl Eq for JsonProjectionMode

impl PartialEq for JsonProjectionMode

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