Struct SourcePos

pub struct SourcePos(/* private fields */);

Swc unfortunately uses BytePos(0) as a magic value. This means that we can’t have byte positions of nodes line up with the text. To get around this, we have created our own SourcePos wrapper that hides the underlying swc byte position so it can’t be used incorrectly.

Implementations

impl SourcePos

pub fn as_byte_pos(&self) -> BytePos

pub fn as_byte_index(&self, start_pos: StartSourcePos) -> usize

pub fn unsafely_from_byte_pos(byte_pos: BytePos) -> Self

Do not use this except when receiving an swc byte position from swc and needing to convert it to a source position. If you need to create a SourcePos then you should get the text info’s start position and add to it in order to get a new source position.
