A parsed FETCH response for a single message (RFC 3501 Section 7.4.2 / RFC 9051 Section 7.5.2).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

seq: u32

Message sequence number (RFC 3501 Section 7.4.2 / RFC 9051 Section 7.5.2).

uid: Option<u32>

UID value (RFC 3501 Section 2.3.1.1).

flags: Option<Vec<Flag>>

FLAGS value (RFC 3501 Section 2.3.2).

envelope: Option<Envelope>

Parsed ENVELOPE (RFC 3501 Section 7.4.2).

body_structure: Option<BodyStructure>

Parsed BODYSTRUCTURE (RFC 3501 Section 7.4.2).

rfc822_size: Option<u64>

RFC822.SIZE in bytes (RFC 3501 Section 7.4.2 / RFC 9051 Section 7.5.2).

RFC 9051 widens this from number to number64 to support messages > 4 GiB.

internal_date: Option<String>

INTERNALDATE timestamp string (RFC 3501 Section 7.4.2).

The date-time string in IMAP format, e.g. "17-Jul-1996 02:44:25 -0700".

body_sections: Vec<BodySection>

Fetched body sections per BODY[section]<partial> (RFC 3501 Section 6.4.5).

mod_seq: Option<u64>

MODSEQ value (RFC 7162 CONDSTORE Section 3.1.3).

save_date: Option<String>

SAVEDATE timestamp string (RFC 8514 Section 3).

The date-time when the message was saved to the mailbox, or None if the server returned NIL (message predates SAVEDATE tracking).

binary_sections: Vec<BinarySection>

BINARY[section] data items (RFC 3516 Section 4.2).

binary_sizes: Vec<(Vec<u32>, u64)>

BINARY.SIZE[section] values (RFC 3516 Section 4.3 / RFC 9051 Section 7.5.2).

Each entry is (section_parts, size_in_bytes). RFC 9051 Section 9 defines the size as number (u32), but stored as u64 for Postel’s-law leniency with servers that send larger values.

preview: Option<String>

PREVIEW text (RFC 8970 Section 3).

A short plaintext snippet of the message, or None if the server returned NIL (e.g., for LAZY requests where the preview is not yet computed).

email_id: Option<String>

EMAILID value (RFC 8474 Section 4).

A server-assigned unique identifier for this particular instance of a message. The value is an objectid string (1-255 alphanumeric/dash/underscore characters).

thread_id: Option<String>

THREADID value (RFC 8474 Section 4).

A server-assigned identifier grouping related messages into threads, or None if the server returned NIL (no thread association).

Trait Implementations

impl Clone for FetchResponse

fn clone(&self) -> FetchResponse

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FetchResponse

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FetchResponse

fn default() -> FetchResponse

Returns the “default value” for a type.

impl Hash for FetchResponse

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FetchResponse

fn eq(&self, other: &FetchResponse) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
