Configuration options for JSON formatting.

This struct contains all settings that control how JSON is formatted. Use Default::default() or FracturedJsonOptions::recommended() to get sensible defaults, then modify individual fields as needed.

Example

use fracturedjson::{FracturedJsonOptions, EolStyle, CommentPolicy};

let mut options = FracturedJsonOptions::default();
options.max_total_line_length = 80;
options.indent_spaces = 2;
options.comment_policy = CommentPolicy::Preserve;

Fields

json_eol_style: EolStyle

Line ending style for the output. Default: EolStyle::Lf.

max_total_line_length: usize

Maximum length of a line before it’s broken into multiple lines. Default: 120.

max_inline_complexity: isize

Maximum nesting depth for arrays/objects to be written on a single line. A value of 0 means only primitive values can be inlined. A value of 1 allows simple arrays/objects with primitive elements. Set to -1 to disable inline formatting entirely. Default: 2.

max_compact_array_complexity: isize

Maximum nesting depth for arrays to use compact multi-line formatting (multiple items per line). Set to -1 to disable. Default: 2.

max_table_row_complexity: isize

Maximum nesting depth for arrays/objects to be formatted as aligned tables. Set to -1 to disable table formatting. Default: 2.

max_prop_name_padding: usize

Maximum number of spaces to use for property name padding in table format. If aligning property names would require more padding than this, alignment is skipped for that container. Default: 16.

colon_before_prop_name_padding: bool

If true, the colon comes before the property name padding. Example with true: "a": 1 vs "aaa": 2 Example with false: "a" : 1 vs "aaa": 2 Default: false.

table_comma_placement: TableCommaPlacement

Where to place commas in table-formatted output. Default: TableCommaPlacement::BeforePaddingExceptNumbers.

min_compact_array_row_items: usize

Minimum number of items required per row when formatting arrays in compact multi-line mode. Default: 3.

always_expand_depth: isize

Depth at which containers are always expanded (never inlined). Containers at this depth or shallower will always be multi-line. Set to -1 to disable (allow inlining at any depth). Default: -1.

nested_bracket_padding: bool

Add spaces inside brackets for nested containers: [ [1, 2] ] vs [[1, 2]]. Default: true.

simple_bracket_padding: bool

Add spaces inside brackets for simple (non-nested) containers: [ 1, 2 ] vs [1, 2]. Default: false.

colon_padding: bool

Add a space after colons in objects: "key": value vs "key":value. Default: true.

comma_padding: bool

Add a space after commas: [1, 2, 3] vs [1,2,3]. Default: true.

comment_padding: bool

Add a space before comments: value /*comment*/ vs value/*comment*/. Default: true.

number_list_alignment: NumberListAlignment

Alignment style for numbers in array tables. Default: NumberListAlignment::Decimal.

indent_spaces: usize

Number of spaces per indentation level. Ignored if use_tab_to_indent is true. Default: 4.

use_tab_to_indent: bool

Use tabs instead of spaces for indentation. Default: false.

prefix_string: String

A string to prepend to every line of output. Useful for embedding formatted JSON within other content. Default: empty string.

comment_policy: CommentPolicy

How to handle comments in the input. Default: CommentPolicy::TreatAsError.

preserve_blank_lines: bool

Preserve blank lines from the input in the output. Only meaningful when comment_policy is not TreatAsError. Default: false.

allow_trailing_commas: bool

Allow trailing commas in the input (non-standard JSON). Default: false.

Implementations

impl FracturedJsonOptions

pub fn recommended() -> Self

Creates a new FracturedJsonOptions with recommended settings.

Currently identical to Default::default(), but may include improved defaults in future versions without breaking compatibility.

Trait Implementations

impl Clone for FracturedJsonOptions

fn clone(&self) -> FracturedJsonOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FracturedJsonOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FracturedJsonOptions

fn default() -> Self

Returns the “default value” for a type.
