Struct FormatPolicy 

pub struct FormatPolicy {
    pub indent_width: usize,
    pub separator: String,
    pub newline: String,
    pub line_break_after: Vec<String>,
    pub indent_open: Vec<String>,
    pub indent_close: Vec<String>,
}

Whitespace and indentation policy applied during emission.

The default policy inserts a single space between adjacent tokens, a newline after ; / } / {, and tracks indent on { / } boundaries. Per-language overrides (idiomatic indent width, trailing-comma rules, blank-line conventions) can ride alongside this struct in a follow-up branch; today’s defaults aim only for syntactic validity.

Fields

indent_width: usize

Number of spaces per indent level.

separator: String

Separator inserted between adjacent terminals that the lexer would otherwise glue together (word ↔ word, operator ↔ operator). Default is a single space.

newline: String

Newline byte sequence emitted after line_break_after tokens and at end-of-output. Default is "\n".

line_break_after: Vec<String>

Tokens after which the walker breaks to a new line.

indent_open: Vec<String>

Tokens that increase indent on emission.

indent_close: Vec<String>

Tokens that decrease indent on emission.
