No import is needed.

Read the usage guide for examples and common tasks. This reference lists the public declarations for this part of the library. See Reading API signatures for parameter and result notation.

byte_size

String payloads use UTF-16; character arrays store full 32-bit values.

public fun byte_size(): int

byte_at

Returns the byte at the zero-based byte index; an invalid index panics.

public fun byte_at(index: int): int

to_string

Returns a text representation of this value.

public override fun to_string(): string

hash_code

Matches string hashing for UTF-16 elements without allocating a string.

public override fun hash_code(): int

equals

Returns whether this value equals other.

public fun equals(borrow other: string): bool

compare

Returns a negative number, zero, or a positive number for less than, equal to, or greater than other.

public fun compare(other: ReadOnlySpan<T>): int

compare

Returns a negative number, zero, or a positive number for less than, equal to, or greater than other.

public fun compare(borrow other: string): int

starts_with

Returns whether this text begins with prefix.

public fun starts_with(borrow prefix: string): bool

ends_with

Returns whether this text ends with suffix.

public fun ends_with(borrow suffix: string): bool

trim

Returns a view without leading or trailing whitespace.

public fun trim(): ReadOnlySpan<T>

trim_start

Returns a view without leading whitespace.

public fun trim_start(): ReadOnlySpan<T>

trim_end

Returns a view without trailing whitespace.

public fun trim_end(): ReadOnlySpan<T>

parse_int

Parses a decimal integer, returning ParseError for invalid or out-of-range input.

public fun parse_int(): Result<int, ParseError>

parse_double

Parses a floating-point number, returning ParseError for invalid input.

public fun parse_double(): Result<double, ParseError>

split_iter

Iterates over segments separated by sep without copying their contents.

public fun split_iter(sep: char): StringSplit

split_iter

Iterates over segments separated by sep without copying their contents.

public fun split_iter(borrow sep: string): StringSplit

lines

Iterates over the lines without copying their contents.

public fun lines(): StringLines
