Struct Extension 

pub struct Extension {
    pub ext_version: u32,
    pub ext_type: [u8; 4],
    pub vendor_id: u16,
    pub critical: bool,
    pub encrypted: bool,
    pub data: Vec<u8>,
}

One EXTD chunk.

Fields

ext_version: u32

Extension format version.

ext_type: [u8; 4]

Four-character ASCII type code.

vendor_id: u16

Vendor identifier, 0 for an ORA standard extension.

critical: bool

Whether a reader that does not implement this extension must refuse the file.

encrypted: bool

Whether the payload is sealed.

data: Vec<u8>

The extension’s own payload.

Implementations

impl Extension

pub fn parse(payload: &[u8], flags: u32) -> Result<Extension>

Parse a payload and its descriptor flags.

pub fn to_bytes(&self) -> Vec<u8>

Serialize the payload.

pub fn to_flags(&self) -> u32

The descriptor flags a writer sets for this extension.

pub fn tag(&self) -> String

The type code as text.

pub fn is_implemented(&self) -> bool

Whether this crate implements the extension.

It implements none: an extension’s payload is vendor-defined and is copied through, never interpreted (section 4.12). A downstream reader that does implement one overrides this.

Trait Implementations

impl Clone for Extension

fn clone(&self) -> Extension

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Extension

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

Formats the value using the given formatter.

impl Eq for Extension

impl PartialEq for Extension

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

Equality operator ==.

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

Inequality operator !=.
