Struct ImageMetadata

pub struct ImageMetadata { /* private fields */ }

Metadata necessary to determine if a payload matches an image without needing to have the actual image.

Implementations

impl ImageMetadata

pub fn new(size: u64, sha256: Sha256, url: AbsoluteComponentUrl) -> Self

Returns new image metadata that designates the given size and hash, which can be found at the given url.

pub fn size(&self) -> u64

Returns the size of the image, in bytes.

pub fn sha256(&self) -> Sha256

Returns the sha256 hash of the image.

pub fn url(&self) -> &AbsoluteComponentUrl

Returns the url of the image.

pub fn for_path( path: &Utf8Path, url: PinnedAbsolutePackageUrl, resource: String, ) -> Result<Self, ImageMetadataError>

Compute the size and hash for the image file located at path, determining the image’s fuchsia-pkg URL using the given base url and resource path within the package.

Trait Implementations

impl Clone for ImageMetadata

fn clone(&self) -> ImageMetadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImageMetadata

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

Formats the value using the given formatter.

impl PartialEq for ImageMetadata

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