Struct StringInput

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

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

Trait Implementations

impl<'a> Clone for StringInput<'a>

fn clone(&self) -> StringInput<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> From<&'a SourceFile> for StringInput<'a>

Creates an Input from [SourceFile]. This is an alias for

   StringInput::new(&fm.src, fm.start_pos, fm.end_pos)

fn from(fm: &'a SourceFile) -> StringInput<'a>

Converts to this type from the input type.

impl Input for StringInput<'_>

fn cur_pos(&self) -> BytePos

TODO(kdy1): Remove this?

fn cur(&self) -> Option<char>

fn peek(&self) -> Option<char>

fn peek_ahead(&self) -> Option<char>

unsafe fn bump(&mut self)

Safety

fn cur_as_ascii(&self) -> Option<u8>

Returns None if it’s end of input or current character is not an ascii character.

fn is_at_start(&self) -> bool

fn last_pos(&self) -> BytePos

unsafe fn slice(&mut self, start: BytePos, end: BytePos) -> &str

Safety

fn uncons_while<F>(&mut self, pred: F) -> &str

where F: FnMut(char) -> bool,

Takes items from stream, testing each one with predicate. returns the range of items which passed predicate.

fn find<F>(&mut self, pred: F) -> Option<BytePos>

where F: FnMut(char) -> bool,

This method modifies [last_pos()] and [cur_pos()].

unsafe fn reset_to(&mut self, to: BytePos)

Safety

fn is_byte(&self, c: u8) -> bool

Implementors can override the method to make it faster.

fn is_str(&self, s: &str) -> bool

Implementors can override the method to make it faster.

fn eat_byte(&mut self, c: u8) -> bool

Implementors can override the method to make it faster.
