Struct Sha256Digest 

pub struct Sha256Digest(pub [u8; 32]);

Tuple Fields

0: [u8; 32]

Implementations

impl Sha256Digest

pub fn from_path(path: &Path) -> Result<Self>

Calculates the SHA256 of a file.

pub fn from_file(f: &mut File) -> Result<Self>

Calculates the SHA256 of an opened file. Note that the underlying file descriptor will have posix_fadvise called on it to optimize for sequential reading.

pub fn from_reader(r: &mut impl Read) -> Result<Self>

Calculates the SHA256 of a reader.

pub fn to_hex_string(&self) -> Result<String>

Trait Implementations

impl Clone for Sha256Digest

fn clone(&self) -> Sha256Digest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sha256Digest

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

Formats the value using the given formatter.

impl Default for Sha256Digest

fn default() -> Sha256Digest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Sha256Digest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Sha256Digest

fn eq(&self, other: &Sha256Digest) -> 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 Sha256Digest

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<Hasher> for Sha256Digest

type Error = Error

The type returned in the event of a conversion error.

fn try_from(hasher: Hasher) -> Result<Self, Self::Error>

Performs the conversion.

impl<W: Write> TryFrom<WriteHasher<W>> for Sha256Digest

type Error = Error

The type returned in the event of a conversion error.

fn try_from(wrapper: WriteHasher<W>) -> Result<Self, Self::Error>

Performs the conversion.
