Function parse_usize

pub fn parse_usize(value: &Value, key: &str) -> Result<usize, SimulationError>

Helper function to parse unsigned integer from YAML

Arguments

• value - YAML value
• key - key to parse

Returns

• usize - parsed value

Errors

• SimulationError - if the value is not a valid unsigned integer

Example

use peng_quad::{parse_usize, SimulationError};
let value = serde_yaml::from_str("key: 1").unwrap();
let result = parse_usize(&value, "key").unwrap();
assert_eq!(result, 1);
