rsonpath-syntax – JSONPath parser

Complete, fast, and fully spec-compliant JSONPath query parser.

Usage

Parse a query to its AST with the parse function.

let query = rsonpath_syntax::parse("$.jsonpath[*]")?;

For advanced usage consult the crate documentation.

Feature flags

There are two optional features:

• arbitrary, which enables a dependency on the arbitrary crate to provide Arbitrary implementations on query types; this is used e.g. for fuzzing.
• color, which enables a dependency on the owo_colors crate to provide colorful Display representations of ParseError with the colored function.

Examples

There are two examples programs, builder showcases usage of the JsonPathQueryBuilder struct; cli is a small CLI tool that takes one argument, a query to parse, and prints a debug representation of the result query, or an error message – this is useful for debugging when developing the crate itself.

State of the crate

This is an in-development version that supports only name, index, and wildcard selectors. However, these are fully supported, tested, and fuzzed. The planned roadmap is:

• support slices
• support filters (without functions)
• support functions (including type check)
• polish the API
• 1.0.0 stable release
