Struct TreeSitterIndenter 

pub struct TreeSitterIndenter { /* private fields */ }

A small Tree-sitter powered indenter driven by an indents.scm query.

This is an optional companion to crate::TreeSitterProcessor:

• The processor focuses on derived state (highlighting/folding).
• The indenter focuses on edit-time indentation decisions (auto-indent on newline).

Query conventions (minimal subset):

• Captures named @indent indicate syntax nodes that increase indentation for their contents.
• Captures named @outdent indicate syntax tokens/nodes that outdent when they begin a line.

Notes:

• This implementation is intentionally conservative; it aims to provide a solid baseline.

Implementations

impl TreeSitterIndenter

pub fn new(config: TreeSitterIndenterConfig) -> Result<Self, TreeSitterError>

Create a new indenter from the given config.

pub fn sync_to_text( &mut self, version: u64, text: &str, ) -> Result<(), TreeSitterError>

Synchronize the indenter with the given editor version and full text.

Notes:

• This API is intentionally “full text” based (no TextDelta required), to make it easy to drive from UI/FFI boundaries.
• Re-parsing is skipped when version is unchanged.

pub fn indent_string_for_line( &self, line: usize, indent_style: IndentStyle, ) -> Option<String>

Compute the desired leading whitespace for a logical line.

Returns None if the indenter is not yet synchronized (call Self::sync_to_text first), or if line is out of range.

pub fn reindent_text_edit_for_line( &self, line: usize, indent_style: IndentStyle, ) -> Option<TextEditSpec>

Build a text edit that replaces the current line’s leading whitespace with the computed Tree-sitter indentation.

Returns None if no change is needed, if the indenter is not synchronized, or if line is out of range.

Trait Implementations

impl Debug for TreeSitterIndenter

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

Formats the value using the given formatter.
