Struct ReplyContext 

pub struct ReplyContext {
    pub thread_id: String,
    pub message_id: Option<String>,
    pub references: Vec<String>,
    pub in_reply_to: Vec<String>,
    pub subject: String,
    pub from: Vec<Mailbox>,
    pub reply_to: Vec<Mailbox>,
    pub to: Vec<Mailbox>,
    pub cc: Vec<Mailbox>,
    pub sent_by_me: bool,
    pub skipped: Vec<(&'static str, String)>,
}

What a reply needs from the message it replies to.

Fields

thread_id: String

Gmail thread id of the original. Goes on the draft’s message, not in a header.

message_id: Option<String>

The original’s Message-ID, without angle brackets.

references: Vec<String>

The original’s References, without angle brackets, in order.

in_reply_to: Vec<String>

The original’s In-Reply-To, without angle brackets.

subject: String

The original’s Subject, or empty.

from: Vec<Mailbox>

The original’s From.

reply_to: Vec<Mailbox>

The original’s Reply-To.

to: Vec<Mailbox>

The original’s To.

cc: Vec<Mailbox>

The original’s Cc.

sent_by_me: bool

Whether the account sent the original (Gmail’s SENT label, which also covers send-as aliases).

skipped: Vec<(&'static str, String)>

Addresses in the original’s address headers that could not be used, as (header, address), for the caller to warn about.

Implementations

impl ReplyContext

pub fn from_message(message: &Message) -> Result<Self>

Reads the reply context from a message fetched with format=metadata and REPLY_HEADERS.

pub fn default_recipients( &self, reply_all: bool, exclude: &[String], ) -> (Vec<Mailbox>, Vec<Mailbox>)

The reply’s To and Cc when the caller names nobody (#1954).

A plain reply goes to the original’s Reply-To, else its From; a reply to a message the account sent goes to that message’s To instead, as in Gmail’s UI. reply_all adds the original’s To to the reply’s To and its Cc to the reply’s Cc, keeping each recipient in the header they were in. The addresses in exclude (the account’s own, and any the caller has already placed) are left out, as are repeats, both compared case-insensitively and keeping the first occurrence (To before Cc).

Either list can come back empty, To included: deciding what that means is the caller’s job.

pub fn reply_references(&self) -> Vec<String>

The reply’s References: the original’s References (or, lacking those, its In-Reply-To) followed by the original’s Message-ID, per RFC 5322 §3.6.4. Duplicates are dropped, keeping the first.

pub fn reply_subject(&self) -> String

Re: <original subject>, unless the original already starts with a Re: (any case, Re : too), so replies don’t stack Re: Re:.
