Struct Message 

pub struct Message {
    pub id: String,
    pub thread_id: Option<String>,
    pub label_ids: Vec<String>,
    pub snippet: Option<String>,
    pub internal_date: Option<String>,
    pub history_id: Option<String>,
    pub size_estimate: Option<i64>,
    pub payload: Option<Value>,
    pub raw: Option<String>,
}

A Gmail message.

Fields

id: String

Gmail message id.

thread_id: Option<String>

Id of the thread this message belongs to.

label_ids: Vec<String>

Labels currently applied to this message.

snippet: Option<String>

A short, plain-text snippet of the message body.

internal_date: Option<String>

Epoch milliseconds as a decimal string — Gmail’s own wire format.

history_id: Option<String>

The mailbox history id at the time this message last changed.

size_estimate: Option<i64>

Estimated size of the message in bytes.

payload: Option<Value>

The parsed MIME structure (headers, body parts). Preserved as raw JSON — see the module doc for why. Present when format is full, metadata, or minimal with parts; absent otherwise.

raw: Option<String>

The full RFC 2822 message, base64url-encoded. Present only when format=raw was requested.

Implementations

impl Message

pub fn internal_date_utc(&self) -> Option<DateTime<Utc>>

Parses Self::internal_date into a UTC timestamp.

Returns None when absent or unparsable — Gmail’s field is a decimal-string epoch-millisecond value; malformed input degrades gracefully rather than erroring.
