Module Slice_bstrSource

Slices on a bigstring (Bstr.t).

This module implements Slice.S: it offers exactly the same API as Slice_bytes (and mirrors Bstr), so that the same code can be used regardless of the underlying byte sequence.

sub and shift are O(1): they share the underlying bigstring with the given slice instead of calling Bstr.sub (which is about 8 times slower).

This module is the result of a poor man's functor designed to avoid the inherent overhead that can arise from using functors in OCaml. In other words, the implementation is the same as that of Slice_bytes.

include Slice.S with type buf = Bstr.t
Sourcetype buf = Bstr.t
Sourcetype nonrec t = buf Slice.t
include Slice.R with type buf := buf and type t := t
Sourceval create : int -> t

create len is a fresh t of length len. Its contents are reset to zero (bytes are set to '\000').

Sourceval make : ?off:int -> ?len:int -> buf -> t

make ~off ~len buf is the view of buf which starts at off (defaults to 0) and which is len bytes long (defaults to length buf - off). The buffer is not copied.

Sourceval init : int -> (int -> char) -> t

init len fn is t of length len with index idx holding the character fn idx (called in increasing index order).

Sourceval empty : t

An empty t.

Sourceval length : t -> int

length t is the length (number of bytes/characters) of t.

Sourceval is_empty : t -> bool

is_empty t is length t = 0.

Sourceval chop : ?rev:bool -> t -> char option

chop t is Some (get t idx) with idx = 0 if rev = false (default) or idx = length t - 1 if rev = true. None is returned if t is empty.

Sourceval hash : t -> int
Sourceval equal : t -> t -> bool
Sourceval constant_equal : t -> t -> bool
Sourceval compare : t -> t -> int
Sourceval get : t -> int -> char

get t i is the byte of t at index i.

Bounds are the ones of the slice, not the ones of the underlying buffer: a slice never gives access to a byte which is outside of its own range.

Sourceval unsafe_get : t -> int -> char

unsafe_get t i is get without any bound checking.

Sourceval get_int8 : t -> int -> int

get_int8 bstr i is bstr's signed 8-bit integer starting at byte index i.

Sourceval get_uint8 : t -> int -> int

get_uint8 bstr i is bstr's unsigned 8-bit integer starting at byte index i.

Sourceval get_uint16_ne : t -> int -> int

get_uint16_ne slice i is slice's native-endian unsigned 16-bit integer starting at byte index i.

Sourceval get_uint16_le : t -> int -> int

get_uint16_le slice i is slice's little-endian unsigned 16-bit integer starting at byte index i.

Sourceval get_uint16_be : t -> int -> int

get_uint16_be slice i is slice's big-endian unsigned 16-bit integer starting at byte index i.

Sourceval get_int16_ne : t -> int -> int

get_int16_ne slice i is slice's native-endian signed 16-bit integer starting at byte index i.

Sourceval get_int16_le : t -> int -> int

get_int16_le slice i is slice's little-endian signed 16-bit integer starting at byte index i.

Sourceval get_int16_be : t -> int -> int

get_int16_be slice i is slice's big-endian signed 16-bit integer starting at byte index i.

Sourceval get_int32_ne : t -> int -> int32

get_int32_ne slice i is slice's native-endian 32-bit integer starting at byte index i.

Sourceval get_int32_le : t -> int -> int32

get_int32_le slice i is slice's little-endian 32-bit integer starting at byte index i.

Sourceval get_int32_be : t -> int -> int32

get_int32_be slice i is slice's big-endian 32-bit integer starting at byte index i.

Sourceval get_int64_ne : t -> int -> int64

get_int64_ne slice i is slice's native-endian 64-bit integer starting at byte index i.

Sourceval get_int64_le : t -> int -> int64

get_int64_le slice i is slice's little-endian 64-bit integer starting at byte index i.

Sourceval get_int64_be : t -> int -> int64

get_int64_be slice i is slice's big-endian 64-bit integer starting at byte index i.

Sourceval filter : (char -> bool) -> t -> t

filter sat slice is a fresh slice made of the bytes of slice that satisfy sat, in the same order.

Sourceval filter_map : (char -> char option) -> t -> t

filter_map fn t is a fresh slice made of the bytes of t as mapped by fn, in the same order.

Sourceval starts_with : prefix:string -> t -> bool
Sourceval is_prefix : affix:string -> t -> bool

is_prefix ~affix slice is true iff affix.[idx] = get slice idx for all indices idx of affix.

Sourceval ends_with : suffix:string -> t -> bool
Sourceval is_suffix : affix:string -> t -> bool

is_suffix ~affix slice is true iff affix.[n - idx] = get slice (m - idx) for all indices idx of affix with n = String.length affix - 1 and m = length slice - 1.

Sourceval is_infix : affix:string -> t -> bool

is_infix ~affix slice is true iff there exists an index j in slice such that for all indices i of affix we have affix.[i] = get t (j + i).
