[−][src]Function gltf_json::deserialize::from_str
pub fn from_str<'a, T>(s: &'a str) -> Result<T, Error> where
T: Deserialize<'a>,
Deserialize an instance of type T
from a string of JSON text.
Example
ⓘThis code runs with edition 2018
use serde::Deserialize; #[derive(Deserialize, Debug)] struct User { fingerprint: String, location: String, } fn main() { // The type of `j` is `&str` let j = " { \"fingerprint\": \"0xF9BA143B95FF6D82\", \"location\": \"Menlo Park, CA\" }"; let u: User = serde_json::from_str(j).unwrap(); println!("{:#?}", u); }
Errors
This conversion can fail if the structure of the input does not match the
structure expected by T
, for example if T
is a struct type but the input
contains something other than a JSON map. It can also fail if the structure
is correct but T
's implementation of Deserialize
decides that something
is wrong with the data, for example required struct fields are missing from
the JSON map or some number is too big to fit in the expected primitive
type.
