Struct Claims 

pub struct Claims {
    pub claims: HashMap<String, String>,
}

Re-exported Claims struct from cclm for accessing JWT claims. The Claims struct holds the claims of a JSON Web Token (JWT).

A JWT is a compact, URL-safe means of representing claims to be transferred between two parties. It consists of a header, a payload, and a signature. The payload is where the claims are stored.

The claims in a JWT are encoded as a JSON object and can be used to convey information such as the identity of an end user, the expiration time of the token, and more.

The Claims struct provides a convenient way to manipulate the claims of a JWT in Rust. It stores the claims as a HashMap<String, String>, allowing for fast and efficient access to each claim.

Fields

claims: HashMap<String, String>

The claims of the JWT as a HashMap.

Implementations

impl Claims

pub fn new() -> Claims

Creates a new instance of the Claims struct with an empty HashMap of claims.

Example

use self::cclm::Claims;
let claims = Claims::new();
assert!(claims.claims.is_empty());

pub fn set_claim(&mut self, key: &str, value: &str)

Adds or updates a claim in the Claims struct with the given key and value.

Example

use self::cclm::Claims;
let mut claims = Claims::new();
claims.set_claim("sub", "1234567890");
assert_eq!(claims.get_claim("sub"), Some(&String::from("1234567890")));

pub fn get_claim(&self, key: &str) -> Option<&String>

Gets a claim from the Claims struct with the given key.

Returns None if the key does not exist in the Claims.

Example

use self::cclm::Claims;
let mut claims = Claims::new();
claims.set_claim("sub", "1234567890");
assert_eq!(claims.get_claim("sub"), Some(&String::from("1234567890")));

pub fn remove_claim(&mut self, key: &str) -> Option<String>

Returns the value of the claim that was removed, if any.

Example

use self::cclm::Claims;
let mut claims = Claims::new();
claims.set_claim("sub", "1234567890");
assert_eq!(claims.remove_claim("sub"), Some("1234567890".to_owned()));

pub fn clear_claims(&mut self)

Clears all claims from the Claims struct.

Example

use self::cclm::Claims;
let mut claims = Claims::new();
claims.set_claim("sub", "1234567890");
claims.clear_claims();
assert!(claims.claims.is_empty());

pub fn has_claim(&self, key: &str) -> bool

Checks if a claim with the given key exists in the Claims struct.

Example

use self::cclm::Claims;
let mut claims = Claims::new();
claims.set_claim("sub", "1234567890");
assert!(claims.has_claim("sub"));

pub fn len(&self) -> usize

Get the number of claims in the Claims struct.

Example

use self::cclm::Claims;
let mut claims = Claims::new();
claims.set_claim("sub", "1234567890");
assert_eq!(claims.len(), 1);

pub fn is_empty(&self) -> bool

Checks if the Claims struct is empty.

Example

use self::cclm::Claims;
let mut claims = Claims::new();
assert!(claims.is_empty());
claims.set_claim("sub", "1234567890");
assert!(!claims.is_empty());

pub fn get_claims(&self) -> &HashMap<String, String>

Get a reference to the HashMap of claims in the Claims struct. This is useful if you need to iterate over the claims.

Example

use self::cclm::Claims;
let mut claims = Claims::new();
claims.set_claim("sub", "1234567890");
claims.set_claim("name", "John Doe");
for (key, value) in claims.get_claims() {
   println!("{}: {}", key, value);
}
