Struct StringInput 

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

Available on crate features __ecma and __parser only.

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 duplicate 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<'a> Input<'a> for StringInput<'a>

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) -> &'a str

Safety

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

where F: FnMut(char) -> bool,

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

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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
