Struct TokenTimer 

pub struct TokenTimer {
    pub expiry: DateTime<Utc>,
    pub last_refreshed: DateTime<Utc>,
    pub max_age: DateTime<Utc>,
}

Timer for managing IG API token expiration and refresh cycles

According to IG API documentation, tokens are initially valid for 6 hours but get extended up to a maximum of 72 hours while they are in use.

Fields

expiry: DateTime<Utc>

The current expiry time of the token (initially 6 hours from creation)

last_refreshed: DateTime<Utc>

The timestamp when the token was last refreshed

max_age: DateTime<Utc>

The maximum age the token can reach (72 hours from initial creation)

Implementations

impl TokenTimer

pub fn new() -> Self

Creates a new TokenTimer with initial 6-hour expiry and 72-hour maximum age

Returns

A new TokenTimer instance with expiry set to 6 hours from now and max_age set to 72 hours from now

pub fn is_expired(&self) -> bool

Checks if the token is expired based on current time

Returns

true if either the token expiry time or maximum age has been reached, false otherwise

pub fn is_expired_w_margin(&self, margin: Duration) -> bool

Checks if the token is expired or will expire within the given margin

Arguments

• margin - The time margin to check before actual expiry

Returns

true if the token will expire within the margin or has already expired, false otherwise

pub fn refresh(&mut self)

Refreshes the token timer, extending the expiry time by 6 hours from now

This should be called after each successful API request to extend token validity. The expiry time is reset to 6 hours from the current time, but cannot exceed max_age.
