Import: import system.text;

last_index_of

The index of the last occurrence of substring sub, or None. Empty sub is Some(length). Byte-compare scan like index_of — allocates nothing per candidate.

public fun last_index_of(borrow sub: string): Option<int>

replace_first

Replaces the first occurrence of old with replacement.

public fun replace_first(borrow old: string, borrow replacement: string): string

split_once

Splits at the first occurrence of sep into exactly two parts. When sep does not occur, returns [this] (consistent with split), never an empty array.

public fun split_once(sep: char): string[]

split_once

Splits at the first occurrence of sep; returns a one-element array when no separator is found.

public fun split_once(borrow sep: string): string[]

strip_prefix

Some remainder when this starts with prefix.

public fun strip_prefix(borrow prefix: string): Option<string>

strip_suffix

Some remainder when this ends with suffix.

public fun strip_suffix(borrow suffix: string): Option<string>

lines

Iterates over the lines without copying them. Lines end at \n; a trailing \r is dropped from each line, and a final line terminator does not produce an empty line. Call to_string() on a line to keep an owned copy.

public fun lines(): StringLines

repeat

A new string repeated times times.

public fun repeat(times: int): string

equals

Value equality (Equatable<string>); identical to this == other.

public fun equals(borrow other: string): bool

split

Splits this string on the single character sep.

public fun split(sep: char): string[]

split

Splits this string on every occurrence of substring sep.

public fun split(borrow sep: string): string[]

split

Splits on sep into at most limit parts (limit < 1 means no limit).

public fun split(sep: char, limit: int): string[]

split

Splits on sep into at most limit parts (limit < 1 means no limit).

public fun split(borrow sep: string, limit: int): string[]

replace

A new string with every occurrence of old replaced by replacement.

public fun replace(borrow old: string, borrow replacement: string): string
