Struct biome_formatter::TransformSourceMapBuilder

pub struct TransformSourceMapBuilder { /* private fields */ }

Builder for creating a source map.

Implementations

impl TransformSourceMapBuilder

pub fn new() -> Self

Creates a new builder.

pub fn with_offset(offset: TextSize) -> Self

pub fn with_source(source: String) -> Self

Creates a new builder for a document with the given source.

pub fn push_source_text(&mut self, text: &str)

Appends text to the source text of the original document.

pub fn add_deleted_range(&mut self, source_range: TextRange)

Adds a new mapping for a deleted character range.

pub fn extend_trimmed_node_range( &mut self, original_range: TextRange, extended_range: TextRange )

Adds a mapping to widen a nodes trimmed range.

The formatter uses the trimmed range when formatting a node in verbatim either because the node failed to format because of a syntax error or because it’s formatting is suppressed with a biome-ignore format: comment.

This method adds a mapping to widen a nodes trimmed range to enclose another range instead. This is e.g. useful when removing parentheses around expressions where (/* comment */ a /* comment */) because the trimmed range of a should now enclose the full range including the ( and ) tokens to ensure that the parentheses are retained when printing that node in verbatim style.

pub fn finish(self) -> TransformSourceMap

Creates a source map that performs single position lookups in O(log(n)).
