Struct json_color::Colorizer

pub struct Colorizer {
    pub null: Color,
    pub boolean: Color,
    pub number: Color,
    pub string: Color,
    pub key: Color,
    // some fields omitted
}

A struct representing a specific configuration of colors for the various JSON components.

Fields

null: Color

boolean: Color

number: Color

string: Color

key: Color

Methods

impl Colorizer

pub fn new() -> ColorizerBuilder

Start builder a new Colorizer.

pub fn arbitrary() -> Self

Creates a new Colorizer with a predefined set of colors for the various JSON components.

Use this if you want your JSON to be colored, but don't care about the specific colors.

pub fn colorize_json_str(&self, s: &str) -> Result<String>

Colorize a JSON string. Currently, all strings will be pretty-printed (with indentation and spacing).

Errors

An error is returned if the string is invalid JSON or an I/O error occurs.

pub fn colorize_to_writer<W>(&self, s: &str, writer: &mut W) -> Result<()> where
    W: Write, 

Colorize a JSON string and write the result to writer.

Currently, all strings will be pretty-printed (with indentation and spacing).

Errors

An error is returned if the string is invalid JSON or an I/O error occurs.
