Struct PortableFormatImage 

pub struct PortableFormatImage { /* private fields */ }

Implementations

impl PortableFormatImage

pub fn empty() -> Self

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

Returns the same-target validation tag stored at the start of every image.

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

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

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

Borrows a static serialized image without allocating or copying its contents.

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

Serialize this format image to a portable byte buffer (a dumped .fmt) that Self::from_bytes can reload. Same-target only — see [PortableTexState::to_portable_bytes].

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

Reload a format image previously produced by Self::to_bytes. Returns None if the buffer is not a format image for this build target.

pub fn state_array_bytes(&self) -> usize

Resident bytes of the engine’s dynamic arrays once instantiated from this image — the dominant runtime memory footprint.

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.
