Struct Output 

pub struct Output<const CAPACITY: usize> {
    pub bytes: [u8; CAPACITY],
    pub length: usize,
}

Const-evaluable output buffer.

With CAPACITY == 0 nothing is stored and only Output::length advances (the measuring pass). With CAPACITY > 0 the bytes are written into bytes, which must be exactly the length the measuring pass reported; anything else is an out-of-bounds const-eval error.

Fields

bytes: [u8; CAPACITY]

The rendered bytes. Meaningful only when CAPACITY is the measured length.

length: usize

The number of bytes rendered.

Implementations

impl<const CAPACITY: usize> Output<CAPACITY>

pub const fn new() -> Self

A fresh, empty writer.

pub const fn put(&mut self, text: &str)

Append a string.

pub const fn put_usize(&mut self, value: usize)

Append a decimal integer.

pub const fn put_quoted(&mut self, text: &str)

Append a string as a double-quoted Javascript literal, escaping backslashes and quotes.

pub const fn put_ident(&mut self, name: &str)

Append an identifier, adding a trailing underscore if it is a reserved word.

pub const fn put_quoted_ident(&mut self, name: &str)

Append an identifier as a quoted string, with the same underscore rule.

pub const fn indent(&mut self, count: usize)

Append count levels of two-space indentation.
