Struct MailIndex 

pub struct MailIndex {
    by_id: BTreeMap<String, MailRef>,
    paths: BTreeMap<String, Vec<PathBuf>>,
}

Messages by Message-ID (without angle brackets).

Fields

by_id: BTreeMap<String, MailRef>

paths: BTreeMap<String, Vec<PathBuf>>

Every file of each Message-ID, in the order found: a message copied into two folders, or another message given the same ID (anyone who knows one can), each kept.

Implementations

impl MailIndex

pub fn build(roots: &[PathBuf], cache: &Path) -> MailIndex

Indexes the Maildirs under roots, reading only what cache does not know yet; the cache is written back.

pub fn get(&self, id: &str) -> Option<&MailRef>

The message with this Message-ID (“abc@x”, “abc@x” or “mid:abc@x”).

pub fn paths(&self, id: &str) -> Vec<PathBuf>

Every file of this Message-ID found here, in the order found.

pub fn insert(&mut self, id: &str, mail: MailRef)

Adds a message known otherwise (a test, a message just sent).

pub fn iter(&self) -> impl Iterator<Item = (&String, &MailRef)>

Every message, by its Message-ID.

pub fn conversations(&self, seeds: &BTreeSet<String>) -> BTreeSet<String>

The messages of the conversations seeds belong to: tied by the ids they answer or cite, through any number of others (RFC 5322 §3.6.4).

pub fn conversations_through( &self, seeds: &BTreeSet<String>, keep: impl FnMut(&str, &MailRef) -> bool, ) -> BTreeSet<String>

The messages of the conversations seeds belong to, as conversations finds them, through the messages keep lets in only (Threads::through).

pub fn threads(&self) -> Threads<'_>

Who cites whom, read once, to follow several projects’ conversations.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
