Struct LineBuffer

pub struct LineBuffer<B: Buffer> { /* private fields */ }

High level interface to line buffer

Implementations

impl LineBuffer<UnboundedBuffer>

pub fn new_unbounded() -> Self

Create new static line buffer

impl<'a> LineBuffer<SliceBuffer<'a>>

pub fn from_slice(buffer: &'a mut [u8]) -> Self

Create new static line buffer

impl<B: Buffer> LineBuffer<B>

pub fn as_slice(&self) -> &[u8]

Return buffer as bytes slice

pub fn len(&self) -> usize

Return buffer length

pub fn as_str(&self) -> &str

Return buffer as string. The buffer should only hold a valid UTF-8, so this function is infallible.

pub fn delete(&mut self, char_index: usize)

Delete character at character index.

pub fn delete_after_char(&mut self, char_index: usize)

Delete buffer after character index

pub fn truncate(&mut self)

Truncate buffer

pub fn delete_previous_word(&mut self, char_index: usize) -> usize

Delete previous word from character index

pub fn swap_chars(&mut self, char_index: usize)

Swap characters at index

pub unsafe fn insert_bytes( &mut self, index: usize, bytes: &[u8], ) -> Result<(), ()>

Insert bytes at index

Safety

The caller must ensure that the input bytes are a valid UTF-8 sequence and that the byte index aligns with a valid UTF-8 character index.

pub fn insert_utf8_char( &mut self, char_index: usize, c: Utf8Char, ) -> Result<(), Utf8Char>

Insert UTF-8 char at position

pub fn insert_str(&mut self, char_index: usize, s: &str) -> Result<(), ()>

Insert string at char position
