Struct ImageHash 

pub struct ImageHash(/* private fields */);

A 256-bit hash for image entries.

This hash is used to identify image files in the IMAGES cache.

Use ImageHasher to compute.

Implementations

impl ImageHash

pub fn compute(data: &[u8]) -> Self

Compute the hash for data.

pub fn hasher() -> ImageHasher

Start a new ImageHasher.

Trait Implementations

impl Clone for ImageHash

fn clone(&self) -> ImageHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageHash

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

Formats the value using the given formatter.

impl Display for ImageHash

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

Formats the value using the given formatter.

impl Hash for ImageHash

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ImageHash

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