Crate use_json 

use-json

Practical JSON utility primitives for lightweight inspection, detection, quoting, and formatting.

Warning: versions below 0.3.0 are experimental and may change as the crate matures.

Example Usage

use use_json::{JsonKind, compact_json_basic, detect_json_kind, quote_json_string};

let compact = compact_json_basic("{ \"ok\": true, \"name\": \"RustUse\" }");
let quoted = quote_json_string("line\nbreak");

assert_eq!(compact, "{\"ok\":true,\"name\":\"RustUse\"}");
assert_eq!(quoted, "\"line\\nbreak\"");
assert_eq!(detect_json_kind("[1, 2, 3]"), JsonKind::Array);

Scope

• small JSON shape and primitive detection helpers
• conservative quoting and escaping helpers for strings
• whitespace compaction that preserves content inside JSON strings

Non-Goals

• a full JSON parser
• JSONPath support
• schema validation
• a replacement for serde_json

is_json_bool

Returns true when the input is a JSON boolean literal.

is_json_null

Returns true when the input is the null literal.

is_json_number

Returns true when the input is a valid JSON number literal.

is_json_string

Returns true when the input is a quoted JSON string.

looks_like_json

Returns true when the input looks like a supported JSON value.

looks_like_json_array

Returns true when the input looks like a JSON array.

looks_like_json_object
