Struct IntlNumbers 

pub struct IntlNumbers(pub &'static dyn Host);

Available on crate feature intl only.

A host with numbers through Intl (feature intl): the number methods here, every other method from the host it wraps — crate::HOST, or a date host (IntlNumbers(&INTL_HOST) for a corpus with dates under datetime-intl). Its own static, like the date hosts, so a client that formats no numbers names a host without this glue (B1′). It forwards each Host method; a method added to the trait later must be forwarded here too.

Trait Implementations

impl Clone for IntlNumbers

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for IntlNumbers

impl Host for IntlNumbers

fn nfc<'a>(&self, s: &'a str, buf: &'a mut String) -> &'a str

The NFC form of s, which failed the quick check (it has a code point at or above U+0300). buf is scratch the result may live in.

fn f64_to_text<'b>(&self, x: f64, buf: &'b mut [u8; 32]) -> Option<&'b str>

The shortest decimal text that round-trips the finite x, written into buf: any form number-literal accepts, with an optional + in the exponent (ryu’s 4.2, 1e21, 1.5e-7 and JavaScript’s String(x) both qualify). None if the host cannot produce it.

fn zone_offset(&self, zone: &str, epoch_ms: i64) -> Option<i32>

The UTC offset, in seconds east, of the IANA time zone zone at the instant epoch_ms (milliseconds since the epoch). None: the host has no zone data, or knows no such zone (the default) — a date/time function that must convert an instant to a named zone then reports Bad Option and a fallback value (datetime.md allows it; a wall time in the wrong zone would be worse).

fn format_date_time( &self, locale: &str, request: &DateTimeRequest<'_>, out: &mut dyn Sink, ) -> bool

datetime-intl: writes request formatted by the host’s date formatter (the browser’s Intl.DateTimeFormat) for locale, and returns true; false (the default) when the host has none.

fn numbers(&self) -> Option<&dyn NumberFormatter>

intl: the host’s number formatter (in the browser Intl.NumberFormat and Intl.PluralRules, when the engine has Intl.NumberFormat v3); None (the default) when it has none — the numeric functions of an intl client then show exact digits and report Unsupported Operation (plans/03-runtime.md §2.7).
