Public Functions¶

contains¶

[Source]

True iff haystack contains needle as a contiguous byte subsequence. Empty needle is always contained (returns true).

fun box contains(
  haystack: String box,
  needle: String box)
: (Bool val | InvalidUtf8 val)

Parameters¶

haystack: String box
needle: String box

Returns¶

(Bool val | InvalidUtf8 val)

starts_with¶

[Source]

True iff haystack begins with prefix.

fun box starts_with(
  haystack: String box,
  prefix: String box)
: (Bool val | InvalidUtf8 val)

Parameters¶

haystack: String box
prefix: String box

Returns¶

(Bool val | InvalidUtf8 val)

ends_with¶

[Source]

True iff haystack ends with suffix.

fun box ends_with(
  haystack: String box,
  suffix: String box)
: (Bool val | InvalidUtf8 val)

Parameters¶

haystack: String box
suffix: String box

Returns¶

(Bool val | InvalidUtf8 val)

index_of¶

[Source]

Byte offset of the first occurrence of needle, or None if absent. Empty needle returns 0.

fun box index_of(
  haystack: String box,
  needle: String box)
: (USize val | None val | InvalidUtf8 val)

Parameters¶

haystack: String box
needle: String box

Returns¶

(USize val | None val | InvalidUtf8 val)

last_index_of¶

[Source]

Byte offset of the last occurrence of needle, or None.

fun box last_index_of(
  haystack: String box,
  needle: String box)
: (USize val | None val | InvalidUtf8 val)

Parameters¶

haystack: String box
needle: String box

Returns¶

(USize val | None val | InvalidUtf8 val)

count¶

[Source]

Non-overlapping occurrences of needle in haystack.

fun box count(
  haystack: String box,
  needle: String box)
: (USize val | InvalidUtf8 val)

Parameters¶

haystack: String box
needle: String box

Returns¶

(USize val | InvalidUtf8 val)

eq¶

[Source]

fun box eq(
  that: Search val)
: Bool val

Parameters¶

that: Search val

Returns¶

Bool val

ne¶

[Source]

fun box ne(
  that: Search val)
: Bool val

Parameters¶

that: Search val

Returns¶

Bool val
