Struct StringInput

pub struct StringInput<'a> { /* private fields */ }
Expand description

Implementation of Input.

Implementations§

§

impl<'a> StringInput<'a>

pub fn new(src: &'a str, start: BytePos, end: BytePos) -> StringInput<'a>

start and end can be arbitrary value, but start should be less than or equal to end.

swc get this value from [SourceMap] because code generator depends on some methods of [SourceMap]. If you are not going to use methods from [SourceMap], you may use any value.

pub fn as_str(&self) -> &str

pub fn bump_bytes(&mut self, n: usize)

pub fn start_pos(&self) -> BytePos

pub fn end_pos(&self) -> BytePos
