Struct ContentHash 

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

A SHA-256 based content hash for detecting changes.

Used to track whether scene files or other content has changed, enabling efficient incremental updates.

Implementations

impl ContentHash

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

Compute a hash from bytes

pub fn from_str(s: &str) -> Self

Compute a hash from a string

pub fn to_hex(&self) -> String

Get the hash as a hex string

pub fn as_bytes(&self) -> &[u8; 32]

Get the raw bytes

pub fn from_file<P: AsRef<Path>>(path: P) -> Result<Self>

Compute a hash from a file’s contents

pub fn to_prefixed_hex(&self) -> String

Get the hash as a prefixed hex string (e.g., “sha256:abcdef…”)

pub fn from_prefixed_hex(s: &str) -> Option<Self>

Parse a prefixed hex string back into a ContentHash

Trait Implementations

impl Clone for ContentHash

fn clone(&self) -> ContentHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentHash

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContentHash

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ContentHash

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

Formats the value using the given formatter.

impl Hash for ContentHash

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 ContentHash

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

impl Serialize for ContentHash

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
