Struct Jq 

pub struct Jq { /* private fields */ }

A wrapper for the jq command.

This can be used to transform a Value using a jq expression.

Example

use dts_core::jq::Jq;
use serde_json::json;
let value = json!([5, 4, 10]);

let jq = Jq::new()?;
let result = jq.process("map(select(. > 5))", &value)?;

assert_eq!(result, json!([10]));

Implementations

impl Jq

pub fn new() -> Result<Jq>

Creates a new Jq instance.

Errors

If the jq executable cannot be found in the PATH or is invalid an error is returned.

pub fn with_executable<P>(executable: P) -> Result<Jq>

where P: AsRef<Path>,

Creates a new Jq instance using the provided executable.

Errors

If executable cannot be found in PATH, does not exist (if absolute) or is invalid an error is returned.

pub fn process(&self, expr: &str, value: &Value) -> Result<Value>

Processes a Value using the provided jq expression and returns the result.

Errors

• Error::Io if spawning jq fails or if there are other I/O errors.
• Error::Json if the data returned by jq cannot be deserialized.
• Error::Message on any other error.
