Enum HeaderExtension

pub(super) enum HeaderExtension {
    BackingFileFormat(String),
    FeatureNameTable(HashMap<(FeatureType, u8), String>),
    ExternalDataFileName(String),
    Unknown {
        extension_type: u32,

    },
}

Header extensions (high-level representation).

Variants

BackingFileFormat(String)

Backing file format string.

FeatureNameTable(HashMap<(FeatureType, u8), String>)

Map of feature bits to human-readable names.

ExternalDataFileName(String)

External data file filename string.

Unknown

Unknown extension.

Fields

extension_type: u32

Type.

data: Vec<u8>

Data (as read).

Implementations

impl HeaderExtension

fn deserialize(ext_type: u32, data: Vec<u8>) -> Result<Option<Self>>

Parse an extension from its type and data. Unrecognized types are stored as Unknown extensions, encountering the end of extensions returns Ok(None).

fn extension_type(&self) -> u32

Return the extension type ID.

fn serialize_data(&self) -> Result<Vec<u8>>

Serialize this extension’s data (exclusing its header).

fn feature_name_table() -> Self

Creates a Self::FeatureNameTable.

Trait Implementations

impl Clone for HeaderExtension

fn clone(&self) -> HeaderExtension

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderExtension

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

Formats the value using the given formatter.

impl PartialEq for HeaderExtension

fn eq(&self, other: &HeaderExtension) -> 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.
