Sets of line positions.
This module implement sets of line positions. They allow to efficiently find the beginning of a line and to convert offset to line and column number.
Exception raised when trying to access a position outside the bounds of a set.
val length : t -> intReturns the length of the set, i.e. the number of characters in the set.
val count : t -> intReturns the number of newlines in the set.
val of_rope : Zed_rope.t -> tof_rope rope returns the set of newline positions in rope.
val empty : tThe empty set.
val width : ?tolerant:bool -> t -> int -> int -> (int, int) Result.resultReturns the width of the given string.
val force_width : t -> int -> int -> intReturns the width of the given string. If error encounted, returns the width of the legit part
val line_index : t -> int -> intline_index set ofs returns the line number of the line containing ofs.
val line_start : t -> int -> intline_start set idx returns the offset of the beginning of the idxth line of set .
val line_stop : t -> int -> intline_stop set idx returns the offset of the end of the idxth line of set .
val line_length : t -> int -> intline_length set idx returns the length of the idxth line of set .
remove set offet length removes length characters at offset in set.
