SyntaxDocument

Struct SyntaxDocument 

Source
pub struct SyntaxDocument { /* private fields */ }
Expand description

A loss-aware YAML document and its original source text.

The underlying concrete syntax tree is intentionally private so ComposeLens can maintain a stable API independently of its parser dependency. Preservation rendering emits the original source without normalization, interpolation, or environment access.

Implementations§

Source§

impl SyntaxDocument

Source

pub fn parse( source_id: SourceId, source: impl Into<Arc<str>>, ) -> Result<SyntaxParse, SyntaxParseError>

Parses YAML into a loss-aware document and structured diagnostics.

Recoverable YAML errors are returned in SyntaxParse::diagnostics while the syntax document remains available. Only sources too large for the concrete syntax tree produce a fatal error.

§Errors

Returns SyntaxParseError when the source exceeds the concrete syntax tree’s byte-offset capacity. Malformed YAML is recoverable and is reported through structured diagnostics.

Source

pub const fn source_id(&self) -> SourceId

Returns the source identifier supplied by the caller.

Source

pub fn source_text(&self) -> &str

Returns the original source text.

Source

pub fn source_span(&self) -> SourceSpan

Returns the span covering the complete source text.

Source

pub fn text(&self, span: SourceSpan) -> Option<&str>

Returns the source text covered by a span from this document.

Source

pub fn line_column(&self, byte_offset: usize) -> Option<LineColumn>

Converts a byte offset in this document to a one-based line and column.

Source

pub fn document_count(&self) -> usize

Returns the number of YAML documents in the stream.

Source

pub fn comment_count(&self) -> usize

Returns the number of comment tokens retained by the concrete syntax tree.

Source

pub fn render_preserved(&self) -> String

Returns the original source as preservation-oriented output.
