Enum PackageValidation 

pub enum PackageValidation {
    None,
    Md5,
    Sha256,
    Pgp,
}

The validation method used during installation of a package.

A validation method can ensure the integrity of a package. Certain methods (i.e. PackageValidation::Pgp) can also be used to ensure a package’s authenticity.

Examples

Parsing from strings:

use std::str::FromStr;

use alpm_types::PackageValidation;

assert_eq!(
    PackageValidation::from_str("none")?,
    PackageValidation::None
);
assert_eq!(PackageValidation::from_str("md5")?, PackageValidation::Md5);
assert_eq!(
    PackageValidation::from_str("sha256")?,
    PackageValidation::Sha256
);
assert_eq!(PackageValidation::from_str("pgp")?, PackageValidation::Pgp);

// Invalid values return an error.
assert!(PackageValidation::from_str("crc32").is_err());

Displaying and serializing:

use alpm_types::PackageValidation;

assert_eq!(PackageValidation::Md5.to_string(), "md5");
assert_eq!(
    serde_json::to_string(&PackageValidation::Sha256).expect("Serialization failed"),
    "\"Sha256\""
);

Variants

None

The package integrity and authenticity is not validated.

Md5

The package is validated against an accompanying MD5 hash digest.

Sha256

The package is validated against an accompanying SHA-256 hash digest.

Pgp

The package is validated using PGP signatures.

Trait Implementations

impl AlpmParser for PackageValidation

fn parser(input: &mut &str) -> Result<Self, ErrMode<ContextError>>

Recognizes a PackageValidation in a string slice.

Errors

Returns an error if input does not begin with a valid variant of PackageValidation.

fn delimiter_error_context<'a, O, P>( parser: P, ) -> impl Parser<&'a str, O, ErrMode<ContextError>>

where P: Parser<&'a str, O, ErrMode<ContextError>>,

Attaches a winnow error context to the parser when a parse error is encountered.

impl AsRef<str> for PackageValidation

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for PackageValidation

fn clone(&self) -> PackageValidation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PackageValidation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PackageValidation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PackageValidation

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

Formats the value using the given formatter.

impl FromStr for PackageValidation

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<PackageValidation, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl PartialEq for PackageValidation

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for PackageValidation

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from( s: &str, ) -> Result<PackageValidation, <Self as TryFrom<&str>>::Error>

Performs the conversion.

impl VariantNames for PackageValidation

const VARIANTS: &'static [&'static str]

Names of the variants of this enum

impl StructuralPartialEq for PackageValidation
