Numbers and quoting: atoi/itoa, parse/format, quote/unquote, and append_*.

`atoi`

XuAPI

pub fn atoi(s &string) int

Purpose

Parse a decimal string as int.

Parameters

s &string: source string (borrowed; caller keeps it; type &string)

Returns

int — a value of this type

`itoa`

XuAPI

pub fn itoa(n int) string

Purpose

Format an int as a decimal string.

Parameters

n int: count, length, or limit (int)

Returns

string — result string

`format_bool`

XuAPI

pub fn format_bool(b bool) string

Purpose

Format as bool.

Parameters

b bool: b (bool)

Returns

string — result string

`parse_bool`

XuAPI

pub fn parse_bool(s &string) bool

Purpose

Parse as bool. Throws on failure.

Parameters

s &string: source string (borrowed; caller keeps it; type &string)

Returns

bool — true or false

`format_int`

XuAPI

pub fn format_int(n int, base int) string

Purpose

Format as int. Throws on failure.

Parameters

n int: count, length, or limit (int)
base int: numeric base (int)

Returns

string — result string

`parse`

XuAPI

pub fn parse(s &string, base int) int

Purpose

Parse the input. Throws on failure.

Parameters

s &string: source string (borrowed; caller keeps it; type &string)
base int: numeric base (int)

Returns

int — a value of this type

`format_uint`

XuAPI

pub fn format_uint(n int, base int) string

Purpose

===================== f64 parsing / formatting (m34) ===================== parse_float / format_float aligned with strconv.ParseFloat(s, 64) and strconv.FormatFloat(f, byte, prec, 64). All decimal<->binary conversion is done with an exact little-endian base-2^30 bignum (no float bits, no recursion); f64 is only touched at the boundary (f64(int) / int(f64) casts and ieee arithmetic), so results are correctly rounded and byte-identical with for the fixture vectors. Throws on failure.

Parameters

n int: count, length, or limit (int)
base int: numeric base (int)

Returns

string — result string

`parse_uint`

XuAPI

pub fn parse_uint(s &string, base int) int

Purpose

Parse as uint. Throws on failure.

Parameters

s &string: source string (borrowed; caller keeps it; type &string)
base int: numeric base (int)

Returns

int — a value of this type

`unquote`

XuAPI

pub fn unquote(s &string) string

Purpose

Unquote and unescape. Throws on failure.

Parameters

s &string: source string (borrowed; caller keeps it; type &string)

Returns

string — result string

`quote_rune`

XuAPI

pub fn quote_rune(r int) string

Purpose

QuoteRune: single-quoted character literal. Printable Unicode is kept as UTF-8; C0/c1 and other non-ASCII-controls use \x / \u / \U. Not a full unicode.IsPrint table — runes >= 0xA0 are emitted as themselves.

Purpose

Whether it is graphic.

Parameters

r int: rune (Unicode code point) (int)

Returns

bool — true or false
