Struct ContentHash 

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

A SHA-256 content hash, displayed as sha256:<hex>.

Implementations

impl ContentHash

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

Compute the SHA-256 hash of raw bytes.

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

Compute the SHA-256 hash of a string.

pub fn from_file(path: &Path) -> Result<Self, NapError>

Compute the SHA-256 hash of a file’s contents.

pub fn parse(s: &str) -> Result<Self, NapError>

Parse a sha256:<hex> string into a ContentHash.

pub fn hex_digest(&self) -> &str

Returns the raw hex digest without the sha256: prefix.

pub fn as_str(&self) -> &str

Returns the full sha256:<hex> string.

pub fn verify(&self, data: &[u8]) -> Result<(), NapError>

Verify that bytes match this hash. Returns an error on mismatch.

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 Eq for ContentHash

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.
