Implementations

impl PieceTable

pub fn new(text: &str) -> Self

Create a new Piece Table from original text

pub fn empty() -> Self

Create an empty Piece Table

pub fn insert(&mut self, offset: usize, text: &str)

Insert text at the specified character offset

pub fn try_insert( &mut self, offset: usize, text: &str, ) -> Result<(), PieceTableError>

Fallible variant of PieceTable::insert that reports piece-table invariant failures.

pub fn delete(&mut self, start_offset: usize, length: usize)

Delete characters in the specified range

pub fn try_delete( &mut self, start_offset: usize, length: usize, ) -> Result<(), PieceTableError>

Fallible variant of PieceTable::delete that reports piece-table invariant failures.

pub fn get_text(&self) -> String

Get the entire document content

pub fn try_get_text(&self) -> Result<String, PieceTableError>

Fallible variant of PieceTable::get_text that reports invalid piece ranges or UTF-8.

pub fn get_range(&self, start_offset: usize, length: usize) -> String

Get text in the specified range

pub fn try_get_range( &self, start_offset: usize, length: usize, ) -> Result<String, PieceTableError>

Get the total character count of the document

pub fn byte_count(&self) -> usize

Get the total byte count of the document

pub fn add_buffer_size(&self) -> usize

Get the size of add_buffer (for memory testing)

pub fn gc(&mut self)

Garbage collection: compact add_buffer, remove unreferenced data

pub fn try_gc(&mut self) -> Result<(), PieceTableError>

Fallible variant of PieceTable::gc that reports invalid add-buffer piece ranges.

pub fn set_gc_threshold(&mut self, threshold: usize)

Set GC threshold
