Enum LineContainer 

pub enum LineContainer {
    Token(LineToken),
    Container {
        children: Vec<LineContainer>,
    },
}

The primary tree structure for the lexer output.

This is a recursive enum representing the complete hierarchical structure of line tokens. Every node in the tree is either a line token or a container of child nodes.

The tree is built by processing Indent/Dedent markers:

• Token variant: A single line token (e.g., SubjectLine, ParagraphLine, ListLine)
• Container variant: A grouped set of child nodes at a deeper indentation level

This structure allows the parser to match patterns by checking token types while maintaining the complete source structure (source tokens, nesting).

Note: Container does NOT store an aggregate source_span. The AST construction facade will compute bounding boxes by recursively unrolling children to their source tokens.

Variants

Token(LineToken)

A single line token

Container

A container of child nodes (represents indented content or grouped lines at same level)

Fields

children: Vec<LineContainer>

Implementations

impl LineContainer

pub fn is_empty(&self) -> bool

Check if this container is empty (only valid for root containers)

Trait Implementations

impl Clone for LineContainer

fn clone(&self) -> LineContainer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LineContainer

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LineContainer

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LineContainer

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

impl Serialize for LineContainer

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
