Enum CheckSums 

pub enum CheckSums {
    Sha256(String),
    Sha512(String),
    None,
}

An enum to allow different checksum types For now there is only sha256 and sha512 all other cases is a CheckSums::None

Variants

Sha256(String)

Sha512(String)

None

Implementations

impl CheckSums

pub fn get_image_checksum_from_checksums_buffer( name: &str, checksums: &Option<String>, filename: &str, ) -> CheckSums

retrieves the checksum of the image named name in the buffer checksums that is the content of a file containing at least one checksum. filename is the filename of that file containing all checksums. We decide with its name the kind of checksums it contains (sha256 or sha512) along with the content of the line that may also be helpful

pub fn verify_file( &self, filename: &str, ) -> Result<Option<bool>, Box<dyn Error>>

Verifies a file’s (named filename) checksum (contained in checksum)

Errors

It will return errors when

• the file cannot be opened
• the file cannot be read
