pub struct Updater<'a> { /* fields omitted */ }

Methods

impl<'a> Updater<'a>

pub fn new(
    rulesets: &'a mut RuleSets,
    update_channels: &'a UpdateChannels,
    storage: &'a dyn Storage,
    default_rulesets: Option<String>,
    periodicity: usize
) -> Updater<'a>

Returns an updater with the rulesets, update channels, storage, and interval to check for new rulesets

Arguments

• rulesets - A ruleset struct to update
• update_channels - The update channels where to look for new rulesets
• storage - The storage engine for key-value pairs
• default_rulesets - An optional string representing the default rulesets, which may or may not be replaced by updates
• periodicity - The interval to check for new rulesets

pub fn perform_check(&mut self)

Perform a check for updates. For all ruleset update channels:

1. Check if new rulesets exist by requesting a defined endpoint for a timestamp, which is compared to a stored timestamp
2. If new rulesets exist, download them along with a signature
3. Verify if the signature is valid, and if so...
4. Store the rulesets

pub fn apply_stored_rulesets(&mut self)

Modify rulesets struct to apply the stored rulesets

pub fn time_to_next_check(&self) -> usize

Return the time until we should check for new rulesets, in seconds

pub fn clear_replacement_update_channels(&self)

Clear the stored rulesets for any update channels which replace the default rulesets. This should be run when a new version of the extension is released, so the bundled rulesets are not overwritten by old stored rulesets.
