Implementations

source

impl Sha256Digest

source

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

Calculates the SHA256 of a file.

source

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.

source

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

Calculates the SHA256 of a reader.

source

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