Struct Parser

pub struct Parser { /* private fields */ }

JSONPath query parser.

Implementations

impl Parser

pub const RECURSION_LIMIT_DEFAULT: usize = 128usize

Default limit on the nesting level of a query.

This can be overridden by ParserBuilder::set_recursion_limit.

pub fn parse(&self, str: &str) -> Result<JsonPathQuery>

Parse a JSONPath query string.

Errors

Fails if the string does not represent a valid JSONPath query as governed by the JSONPath RFC specification.

Note that leading and trailing whitespace is explicitly disallowed by the spec. The parser defaults to this strict behavior unless configured with ParserBuilder::allow_surrounding_whitespace.

There is a limit on the complexity of the query measured as the depth of nested filter expressions. This limit defaults to RECURSION_LIMIT_DEFAULT and can be overridden with ParserBuilder::set_recursion_limit.
