Struct PortableFormatImage 

pub struct PortableFormatImage { /* private fields */ }

A sealed engine state, decoded and validated once when loaded, that every engine instance clones.

Implementations

impl PortableFormatImage

pub fn empty() -> Self

The image of a state before initialize_format_state, engines built from it only initialize.

pub fn validation_tag() -> [u8; 17]

Returns the validation tag stored at the start of every image this build writes.

pub fn bytes_match_target(bytes: &[u8]) -> bool

Reports whether a serialized image carries this build’s validation tag.

pub fn from_static_bytes(bytes: &'static [u8]) -> Result<Self, FormatImageError>

Decodes and validates a static image once, later instantiation only clones the decoded state.

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

Serializes this image, the bytes are deterministic and load in this build on any target of the same byte order.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, FormatImageError>

Decodes and validates an image produced by Self::to_bytes.

pub fn state_array_bytes(&self) -> usize

Resident bytes of the engine arrays once instantiated from this image.

Trait Implementations

impl Clone for PortableFormatImage

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
