Crate liver_shot 

A lightweight, no_std JSON value position extractor.

Returns a Span (start/end byte offsets) rather than a parsed value.

Limitations

• Object navigation only - arrays at the top level or as a path step return Error::is_unsupported_array.
• Values are not validated — only their position is extracted.

Examples

Extract an object

let json = r#"{"a": {"b": "value", "c": [1, 2, 3]}}"#;

let span = liver_shot::find("a", json)?;
assert_eq!(r#"{"b": "value", "c": [1, 2, 3]}"#, span.get(json));

Extract a nested object

let json = r#"{"a": {"b": {"c": "value"}}}"#;

let span = liver_shot::find("a.b", json)?;
assert_eq!(r#"{"c": "value"}"#, span.get(json));

Extract an array

let json = r#"{"a": {"b": "value", "c": [1, 2, 3]}}"#;

let span = liver_shot::find("a.c", json)?;
assert_eq!("[1, 2, 3]", span.get(json));

Reuse Span

let json = r#"{"a": {"b": "value", "c": [1, 2, 3]}}"#;

let a = liver_shot::find("a", json)?;
let b = a.find("b", json)?;
let c = a.find("c", json)?;

assert_eq!(r#"{"b": "value", "c": [1, 2, 3]}"#, a.get(json));
assert_eq!(r#""value""#, b.get(json));
assert_eq!("[1, 2, 3]", c.get(json));
