Struct QuickJsSourceLocator 

pub struct QuickJsSourceLocator<'source> { /* private fields */ }

Convert authoritative source-buffer byte offsets with pinned QuickJS’s exact get_line_col rules: LF is the only newline and bytes shaped like UTF-8 continuations do not advance the column. Raw parser inputs need not themselves be valid UTF-8.

Implementations

impl<'source> QuickJsSourceLocator<'source>

pub const fn new(source: &'source str) -> Self

pub const fn from_bytes(source: &'source [u8]) -> Self

pub fn locate( self, offset: SourceOffset, ) -> Result<LineColumn, DebugMetadataError>

pub fn locate_byte_offset( self, byte_offset: usize, ) -> Result<LineColumn, DebugMetadataError>

pub fn index(self) -> Result<QuickJsSourceIndex<'source>, DebugMetadataError>

Prepare bounded-distance lookups for consumers with many source sites. One-off diagnostics can keep using the allocation-free locator.
