Struct CabalCst 

pub struct CabalCst {
    pub source: String,
    pub nodes: Vec<CstNode>,
    pub root: NodeId,
}

The concrete syntax tree for a .cabal file.

All Spans reference byte offsets into source.

Fields

source: String

The original source text (owned).

nodes: Vec<CstNode>

Flat arena of all CST nodes.

root: NodeId

Index of the root node (always NodeId(0)).

Implementations

impl CabalCst

pub fn render(&self) -> String

Render the CST back to text. When no edits have been made, this must produce byte-identical output to the original source.

pub fn node_count(&self) -> usize

Number of nodes in the arena.

pub fn node(&self, id: NodeId) -> &CstNode

Get a reference to a node by its id.

pub fn node_mut(&mut self, id: NodeId) -> &mut CstNode

Get a mutable reference to a node by its id.

pub fn children(&self, id: NodeId) -> &[NodeId]

Iterate over the direct children of a node.

Trait Implementations

impl Clone for CabalCst

fn clone(&self) -> CabalCst

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CabalCst

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

Formats the value using the given formatter.
