Struct mobi::headers::ExtHeader

pub struct ExtHeader {
    pub identifier: u32,
    pub header_length: u32,
    pub record_count: u32,
    pub records: IndexMap<ExthRecord, Vec<Vec<u8>>>,
}

Optional header containing extended information. If the MOBI header indicates that there’s an EXTH header, it follows immediately after the MOBI header.

Fields

identifier: u32

header_length: u32

record_count: u32

records: IndexMap<ExthRecord, Vec<Vec<u8>>>

Implementations

impl ExtHeader

pub fn get_record_position(&self, position: u32) -> Option<&Vec<Vec<u8>>>

Returns exth record data located at position. This is a low level function intended to use with wrapper get_record, but exposed for convienience.

pub fn get_record(&self, record: ExthRecord) -> Option<&Vec<Vec<u8>>>

Returns exth record data. This function limits possible queried records to only those commonly available among mobi ebooks.

pub fn raw_records(&self) -> impl Iterator<Item = (&ExthRecord, &Vec<Vec<u8>>)>

Returns an iterator over all available raw EXTH records.

pub fn records(&self) -> impl Iterator<Item = (&ExthRecord, Vec<String>)>

Returns an iterator over all available EXTH records and performs a loseless conversion of record data to string.

Trait Implementations

impl Debug for ExtHeader

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

Formats the value using the given formatter.

impl Default for ExtHeader

fn default() -> ExtHeader

Returns the “default value” for a type.

impl PartialEq<ExtHeader> for ExtHeader

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

This method tests for self and other values to be equal, and is used by ==.

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

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