Struct ropey::RopeSlice
[−]
[src]
pub struct RopeSlice<'a> { /* fields omitted */ }An immutable view into part of a Rope.
Methods
impl<'a> RopeSlice<'a>[src]
fn len_bytes(&self) -> usize[src]
Total number of bytes in the RopeSlice.
fn len_chars(&self) -> usize[src]
Total number of chars in the RopeSlice.
fn len_lines(&self) -> usize[src]
Total number of lines in the RopeSlice.
fn char_to_line(&self, char_idx: usize) -> usize[src]
Returns the line index of the given char.
fn line_to_char(&self, line_idx: usize) -> usize[src]
Returns the char index of the start of the given line.
fn get_char(&self, char_idx: usize) -> char[src]
Returns the char at char_idx.
fn get_line(&self, line_idx: usize) -> RopeSlice<'a>[src]
Returns the line at line_idx.
Note: lines are zero-indexed.
fn is_grapheme_boundary(&self, char_idx: usize) -> bool[src]
Returns whether char_idx is a grapheme cluster boundary or not.
fn prev_grapheme_boundary(&self, char_idx: usize) -> usize[src]
Returns the char index of the grapheme cluster boundary to the left
of char_idx.
This excludes any boundary that might be at char_idx itself, unless
char_idx is at the beginning of the rope.
fn next_grapheme_boundary(&self, char_idx: usize) -> usize[src]
Returns the char index of the grapheme cluster boundary to the right
of char_idx.
This excludes any boundary that might be at char_idx itself, unless
char_idx is at the end of the rope.
fn slice(&self, start: usize, end: usize) -> RopeSlice<'a>[src]
Returns an immutable slice of the RopeSlice in the char range start..end.
fn bytes(&self) -> RopeBytes<'a>[src]
Creates an iterator over the bytes of the RopeSlice.
fn chars(&self) -> RopeChars<'a>[src]
Creates an iterator over the chars of the RopeSlice.
fn graphemes(&self) -> RopeGraphemes<'a>[src]
Creates an iterator over the grapheme clusters of the RopeSlice.
fn lines(&self) -> RopeLines<'a>[src]
Creates an iterator over the lines of the RopeSlice.
fn chunks(&self) -> RopeChunks<'a>[src]
Creates an iterator over the chunks of the RopeSlice.
fn to_string(&self) -> String[src]
Returns the entire text of the RopeSlice as a newly allocated String.
fn to_rope(&self) -> Rope[src]
Creates a new Rope from the contents of the RopeSlice.
