Struct InlineYEncBlock 

Source
#[non_exhaustive]
pub struct InlineYEncBlock { pub begin_offset: u32, pub begin_length: u32, pub filename: String, pub file_size: u64, pub part: Option<u32>, pub total_parts: Option<u32>, pub part_begin: Option<u64>, pub part_end: Option<u64>, pub data: Vec<u8>, pub crc32_verified: bool, pub is_encoding_problem: bool, }
Expand description

A single yEnc-encoded block found inside a part body.

All byte offsets are absolute — they are in the same coordinate space as ParsedPart::body_range and the raw buffer passed to scan_inline_yencode().

Fields (Non-exhaustive)§

This struct is marked as 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.
§begin_offset: u32

Byte offset of the =ybegin line within raw.

Slicing raw[begin_offset .. begin_offset + begin_length] yields the complete yEnc article from the =ybegin line through the =yend line (inclusive of its line ending).

§begin_length: u32

Byte length of the entire block: from the start of =ybegin through the end of =yend (inclusive of its newline).

When [is_encoding_problem] is true, this field holds the length of the =ybegin line only (up to and including its newline), not the full block through =yend. The =yend line could not be located because decoding failed before it was reached. Do not rely on begin_offset + begin_length spanning a complete block when is_encoding_problem is set.

§filename: String

Filename from the name= field of =ybegin.

Not sanitised against path traversal. Callers writing this to disk must validate against .. and absolute paths.

Empty when [is_encoding_problem] is true and the block header could not be parsed.

§file_size: u64

Total declared file size in bytes, from =ybegin size=. For multi-part articles this is the size of the complete file, not just this part.

When [is_encoding_problem] is true, this field is 0 and does not reflect a declared size (the header could not be parsed).

§part: Option<u32>

1-based part number from =ybegin part=. None for single-part articles.

§total_parts: Option<u32>

Total number of parts in the series from =ybegin total=. None for single-part articles.

§part_begin: Option<u64>

1-based byte offset of the first byte of this part within the full file, from =ypart begin=. None for single-part articles.

§part_end: Option<u64>

1-based byte offset of the last byte of this part within the full file, from =ypart end=. None for single-part articles.

§data: Vec<u8>

Decoded binary payload.

§crc32_verified: bool

true if the CRC32 in =yend was present and matched the decoded bytes. false if no CRC field was present in the article (some older encoders omit it).

§is_encoding_problem: bool

true if any decoding error was encountered (missing =ybegin, invalid header field, missing =yend, CRC mismatch, or any other error returned by yencoding::decode).

When this is true, data may be empty or partial. The specific yEnc error variant is not exposed — callers only see this boolean flag. The underlying yencoding::YencError is consumed internally to populate the sentinel fields; inspect data.is_empty(), crc32_verified, and begin_length to distinguish failure modes.
